My mother-in-law Cynthia moved in, and soon after, my daughter Lisa began acting oddly. She was no longer her cheerful self, and it worried me deeply. One night, I saw her sleepwalking through the house, clutching her teddy bear. I quietly followed her, and what I discovered that night shocked me, leading to a bigger mystery I needed to solve.
We were a happy family, living together in peace. Our days were filled with laughter, playful moments with our daughter, Lisa, and cozy family dinners.
Tony worked as a financial analyst, always dreaming of starting his own business, while I balanced my career and took care of our home.

One evening, Tony came home with exciting news.
“Amelie, I found partners, and I can finally start my own business, just like I’ve always dreamed!” he announced, grinning from ear to ear.
“That’s amazing, Tony!” I hugged him, feeling proud. “You’ve worked so hard for this.”

“There’s something I need to talk to you about,” he said, looking a bit hesitant.
“With our new jobs, we’ll be even busier. Mom has been complaining about her health and suggested moving in with us. She wants to help with taking care of Lisa.”
I frowned.
“Tony, you know how Cynthia feels about our marriage. She never really accepted me.”
“I know, but she insisted,” Tony replied. “And we really could use the help right now.”

I sighed, unsure.
“Alright, but only because we need the help. And of course, she wants to move in now that things are looking up for us.”

A few days later, Cynthia moved in. She entered the house with a big smile, her hands held in front of her, carrying a gift for Lisa.
“Hello, Lisa! Look what Grandma brought you,” she said, handing Lisa a fluffy teddy bear.
“Thank you, Grandma!” Lisa hugged the bear tightly, her eyes sparkling with joy.

Tony looked at me, hoping I would make an effort. “Thanks, Cynthia. I’m sure Lisa will love it,” I said, forcing a smile.
“Amelie, I know we’ve had our differences,” Cynthia began. “But I want to make this work for Tony and Lisa.”
“I hope so,” I replied cautiously.
***
Days turned into weeks, and I noticed changes in Lisa. She became cranky and sleepy during the day. She wasn’t her usual cheerful self, and it worried me.

“Lisa, honey, why are you so tired?” I asked one afternoon as she rubbed her eyes.
“I don’t know, Mommy. I just feel sleepy,” she replied, yawning.
That night, as I checked on her, I saw her walking around. Her eyes were closed, and she seemed to be in a daze.

“Lisa, sweetie, what are you doing?” I whispered, gently taking her by the hand.
She didn’t respond, just continued clutching the teddy bear. I carefully guided her back to bed and tucked her in, feeling a knot of worry in my stomach.
The next morning, over breakfast, I decided to bring it up with Tony.
“Tony, I saw Lisa sleepwalking last night,” I said, trying to keep my voice calm. “She was wandering around with that teddy bear your mom gave her.”

Tony looked surprised. “Really? That’s strange.”
Before he could say more, Cynthia, walking nearby, chimed in.
“Oh, that’s perfectly normal. Tony used to sleepwalk as a child too. There’s nothing to worry about,” she said with a dismissive wave of her hand.
“Are you sure?” I asked, looking at her thoughtfully.
“Absolutely. It’s just a phase,” Cynthia insisted, her tone final.

I nodded, but the worry didn’t leave me. Later that morning, as Tony was getting ready for work, he suddenly frowned and checked his wallet.
“Amelie, have you seen some money I left in my wallet? It’s missing,” he said, looking puzzled.
“No, I haven’t touched your wallet,” I replied honestly.
Tony sighed. “Maybe I misplaced it. It’s probably just somewhere around.”

I decided to get my purse to give my husband some money. But I was surprised to find a much larger sum than I had yesterday.
“Tony, look at this. Is this the amount you were missing?” I said, showing him the money.
Tony peered into the purse and nodded. “Yes, that’s exactly how I tied and stored the amount in my wallet yesterday. That’s strange. Maybe you took it by mistake?”
I shook my head. “No, I’m sure I didn’t. It’s really odd.”
How did it get there?

Tony shrugged, trying to brush it off. “Let’s not worry about it.”
But I couldn’t shake off the uneasy feeling. Something was definitely wrong, and I needed to figure out what was happening. That night, I couldn’t sleep, thinking about Lisa and the strange occurrences.

The next few days, I kept a closer eye on Lisa. She was still cranky and tired during the day, and I noticed she clung to the teddy bear more than usual.
I decided to follow her if she sleepwalked again, to see if I could find any answers.
That night, it happened again. I saw Lisa get up from her bed, holding the teddy bear tightly in her arms. This time, her eyes were wide open, but she didn’t seem to notice me.

She walked out of her room and down the hallway. I quietly followed her, making sure not to wake her. My heart pounded as I watched her small figure move through the dimly lit house.
This time, she went straight to Cynthia’s room. I paused outside the door, straining to hear. I heard Cynthia’s voice, low and insistent.
“Go to your parents’ room… Take the money from the safe, Lisa. Remember, it’s our little secret.”

For illustration purposes only | Source: Pexels
My blood ran cold. I couldn’t believe what I was hearing. I stood frozen for a moment, then hurried back to my room to wake Tony.
“Tony, wake up! You have to see this,” I whispered urgently, shaking him awake.
Tony groggily opened his eyes. “What’s going on, Amelie?”

For illustration purposes only | Source: Pexels
“It’s Lisa. She’s in your mom’s room. I heard Cynthia giving her instructions to take money from the safe,” I said, my voice trembling.
Tony sat up, looking frustrated. “Amelie, you’re overreacting. Mom wouldn’t do that.”
“Please, Tony, just come and see,” I begged.
Reluctantly, he got out of bed and followed me to Cynthia’s room. We quietly opened the door and saw both Cynthia and Lisa seemingly asleep. Tony sighed in exasperation.

“See, they’re both asleep. You’re making a big deal out of nothing,” he said, rubbing his temples.
“No, Tony, I know what I heard,” I insisted.
Frustrated, Tony stomped over to the safe.
“I’ll prove to you that this is all a misunderstanding. The money should be right here. I was going to invest it in my project tomorrow.”

Then Tony’s face went pale.
“What? No, this has to be a joke. The money was here this morning!” he shouted, his voice filled with anger.
“Tony, it’s not a joke. Your mother is responsible for this,” I said firmly.
The commotion woke everyone up. Cynthia came into the room, looking defensive.
“What’s all this noise about?”

For illustration purposes only | Source: Midjourney
Tony turned to her, fury in his eyes. “Mom, did you ask Lisa to steal money from the safe?”
Cynthia’s eyes widened, and she started to deny it. “Of course not! How could you even think that?”
Just then, Lisa started to cry, scared and confused by the shouting. I knelt down and gently took her hand.

“Lisa, sweetie, can you tell us what happened? It’s important.”
Lisa sniffled and nodded. She walked over to my purse and pointed.
Tony looked inside my purse and found the missing money. His face contorted with rage and disbelief.

For illustration purposes only | Source: Pexels
“Amelie, how could you? Were you trying to frame my mother?”
“No, Tony! I didn’t know the money was there! It was your mother’s doing!” I protested.
But Tony was too angry to listen.
“This is too much. I can’t deal with this right now. Amelie, I think it’s best if you stay somewhere else for a while. Mom will watch over Lisa.”
“Tony, please, you have to believe me. I’m not the one at fault here!” I pleaded, tears streaming down my face.

Cynthia stood behind Tony, a look of satisfaction hidden in her eyes.
“It’s for the best, Amelie. We need some time to sort this out.”
My heart was breaking, but I knew I had to find a way to prove the truth and protect my family.
***
In the morning, Tony left for work while I started packing my things. My heart was heavy with sadness and frustration.

As I gathered my belongings, I went into Lisa’s room and noticed her sitting on the bed, talking to the teddy bear.
“Lisa, sweetie, who are you talking to?” I asked gently, trying not to startle her.
She looked up at me with big, innocent eyes.
“The teddy bear, Mommy. But it doesn’t want to talk anymore.”

For illustration purposes only | Source: Pexels
I frowned, feeling a knot of worry. “What do you mean, it doesn’t want to talk anymore?”
Lisa hugged the bear tightly.
“It used to talk to me before bedtime. Grandma said it was our little secret.”
My heart sank. This was worse than I had imagined.
“Lisa, can I borrow the teddy bear for a bit? I need to wash it,” I said, trying to sound casual.

For illustration purposes only | Source: Pexels
She hesitated, then answered, “Okay, Mommy. Just be careful with him.”
I didn’t leave the house. I was waiting for the evening to put everything in its place. I had a hunch about what was happening and who was behind it all.
***
That evening, while preparing dinner, Cynthia entered the kitchen. She stood there with her arms crossed, looking smug.

“Why haven’t you left yet, Amelie? Tony doesn’t want a thief in his house.”
I took a deep breath, trying to stay calm. “I have some unfinished business, Cynthia. Everything will be resolved when Tony returns.”
Cynthia’s eyes narrowed. “What are you planning?”
“You’ll see,” I replied, turning back to the stove.

When Tony came home, I was ready.
“Tony, I need to show you something,” I said, holding the teddy bear.
He looked weary. “What is it now, Amelie?”
“Please, just trust me,” I urged.
I brought out the teddy bear and carefully opened it, revealing a small talking device inside.

“Tony, Lisa wasn’t sleepwalking. She was being manipulated by this device. Cynthia has been using it to give her instructions.”
“That’s ridiculous!” Cynthia shouted, her face turning red. “You’re making this up!”
“Let’s check Cynthia’s room for the other half of the device,” I suggested, keeping my voice steady.
Cynthia backed away, her eyes wide with fear. “No, you can’t go in there!”
Tony, now suspicious, insisted, “Mom, we need to see.”

I pressed the button on the bear’s device and spoke into it. At that moment, we heard my voice echoing from Cynthia’s room.
Tony rushed in and found the other device hidden under Cynthia’s pillow.
Lisa, hearing the commotion, peeked into the room. “Grandma, are we playing a new game since our secret is out?”

For illustration purposes only | Source: Midjourney
Tony looked puzzled. “Mom, how did you use the bear to control her?”
Cynthia sighed, wiping her tears. “I put a walkie-talkie inside the teddy bear and another one under my pillow. When Lisa would start sleepwalking, I would whisper instructions to her through the bear. I would tell her to come to my room, and we would play a game. She would take money from your wallet and put it in her mom’s purse, and then back again.”
“Mom, why? Why would you do this?” Tony exclaimed.
In tears, Cynthia finally broke down.

For illustration purposes only | Source: Pexels
“At first, it was just to see if it would work. Then it became a way for me to feel in control, to have a role in the family. I didn’t realize how much it would hurt everyone.”
Tony, filled with anger and disappointment, shook his head.
“Mom, this is wrong. You can’t use Lisa like that. If you want to be part of this family, you have to stop these manipulations and respect our lives.”
Realizing her mistakes, Cynthia nodded, her face wet with tears.
“I’m sorry, Tony,” Cynthia said, her voice trembling with emotion.

“I just wanted to feel needed. I promise I’ll do better. I’ll only visit on weekends and spend time with Lisa occasionally.”
Tony looked at me. “Amelie, what do you think?” he asked softly.
I took a deep breath, trying to hold back my tears.
“Cynthia, we all make mistakes. But if you truly want to be part of this family, you need to accept us and respect our boundaries. I think it would be good for Lisa to spend time with her grandmother.”

For illustration purposes only | Source: Pexels
Cynthia nodded, wiping her tears.
“I understand. I’ll respect your family’s peace and unity.”
I smiled faintly, looking at my sleepy daughter and feeling a glimmer of hope.
“Let’s take it one step at a time and work together to create a loving environment for Lisa.”

For illustration purposes only | Source: Pexels
Cynthia reached out and took my hand.
“Thank you, Amelie. I promise I’ll make it right.”
The truth was finally out, and now we could begin the process of rebuilding our trust and unity. It wouldn’t be easy, but with love and understanding, we could overcome this challenge together.

If you enjoyed this story, read this one: Six-year-old Ethan had recently lost his mother, leaving a deep void in his heart. In his grief, he started writing letters to her, pouring out his feelings on paper. One day, while wandering the streets, he stumbled upon an old, rusty mailbox at an abandoned house. He decided to slip one of his letters inside, never expecting anyone to see it. To his astonishment, the very next day, he found a mysterious reply waiting for him.
My Husband’s Cousin Came to Stay with Us Temporarily with Her Child – If Only I Had Known It Was All a Setup

When Derek’s cousin Daisy and her son arrive, it seems like an innocent favor. But strange comments, awkward glances, and hidden tension hint at a darker truth. Then comes the devastating revelation: Daisy isn’t his cousin, and Patrick isn’t his nephew. Shattered by betrayal and blindsided by lies, Rebecca is forced to unravel the secrets her husband tried to bury. Can trust survive a truth this explosive, or is it already too late?
When my husband told me his cousin Daisy and her son Patrick needed a place to stay for a couple of weeks, I didn’t think twice. He said they’d fallen on hard times and just needed a little help to get back on their feet.
“Of course,” I said. “Family is family.”

I mean, really? Before Derek and I were married, I had financial issues, too. It had been a struggle and a half to get myself out of my study loan debt, among other things.
So, what would it say about me if I didn’t reach out to help my husband’s family?
That was a month ago. If only I knew how deeply those words would cut.

A woman sitting on a couch | Source: Midjourney
When Daisy and Patrick arrived, everything seemed fine. At first, Daisy was polite but reserved, and I chalked it up to shyness. She wasn’t particularly warm toward me, but toward Derek?
She was a different person altogether!
She was animated, laughing at his jokes and chatting like they’d known each other forever. I ignored the faint flicker of discomfort that rose in my chest.

They were family.
Right?
Patrick, though, was another story. At first, he was just an energetic eight-year-old. But within days, he turned into a whirlwind of chaos.

Crumbs littered the living room floor, sticky handprints appeared on the walls, and his toys became landmines scattered across the house.
The worst part?
He didn’t listen. I once asked him to clean up after himself, and he threw a tantrum, flinging cushions from the couch.
“You’re not my mother!” he shrieked. “I don’t listen to you!”
I finally had enough one evening.

“Patrick,” I said firmly, abandoning the light and caring attitude I wanted to initially use with him. “I need you to understand that you’re a guest here. Act properly. Behave. This isn’t your home.”
His reply made my stomach drop.
“No, Rebecca,” he said, spitting out my name. “My mom told me this is our home now.”
I stared at him, unsure if I’d heard him right.

A shocked woman | Source: Midjourney
Excuse me?
It had to be a misunderstanding, I told myself. Kids misinterpret things all the time, and Daisy probably said it to make the move easier on him.
But his words stayed with me, a tiny splinter in the back of my mind.
The real unraveling began a week later, during a casual lunch with Derek’s sister, Ashley. She’d come by to invite us to a family dinner, and the three of us were sitting outside, enjoying lemonade and plates of spaghetti. Daisy had taken Patrick for ice cream and a walk to the park.

At some point, she turned to me with a warm smile.
“You’re a saint for letting them stay here, Becca,” she said.
I waved her off with a laugh, spearing a meatball with my fork.
“Stop it! It’s your family. How could I turn your cousin and nephew away? Why wouldn’t I let them stay?”

Her fork froze midway to her mouth.
“Wait. So he didn’t tell you?” she gasped.
My chest tightened.
“Tell me what? Ash? Derek?”
Ashley’s eyes darted to Derek, who was suddenly very interested in his glass of lemonade.

“Oh, my god. Becca…” she whispered. “You really don’t know…”
“Know what?” My voice wavered as the splinter in my mind turned into a dagger.
Ashley’s face paled.
“Daisy isn’t our cousin, Becca,” she blurted out. “She’s Derek’s ex-girlfriend. And Patrick? He’s their son.”
The room tilted.

I had to grip hard onto the edge of the table to steady myself, my pulse pounding in my ears.
“What are you talking about?” I croaked, though deep down, I already knew the answer.
Ashley looked stricken.
“I thought you knew, Becca! Derek told the whole family he’d explained everything to you. Our mother told him that he had to tell you the truth before you got married. Daisy was raising Patrick with her then-boyfriend, but Derek was sending child support to them!”

She sighed deeply, remorse filling her lungs. I knew she hated being the one to tell me.
Then, her gaze snapped to him.
“You said you told her!”
Derek didn’t meet my eyes. My stomach churned as every odd moment from the past month clicked into place.

An upset woman | Source: Midjourney
Daisy’s reserved demeanor around me, her easy laughter with Derek, Patrick’s defiant declaration. I felt like the biggest fool on earth.
I stood abruptly, my chair scraping against the floor.
“You have to get back to work. I have to clean up here and log onto a meeting. I will be at your office in two hours. And you’re going to explain everything.”
Derek’s face clouded and then cleared. He nodded.

“Fine. I’ll push my meetings, Becs,” he said, leaving.
“I’m so sorry, Rebecca,” Ashley said, picking up the empty plates. “I truly thought that Derek was a man of his word.”
“It’s not your fault, babe,” I said. “This is on him. But I need you to know that whatever happens next has nothing to do with you. Okay?”
She nodded meekly and began to wash the dishes.

At Derek’s office, I waited in a small conference room, my heart still hammering. When Derek walked in, he looked like he’d aged ten years in the span of an hour.
He sat across from me, his shoulders slumped.
“Start talking,” I demanded.
He exhaled shakily, avoiding my gaze.

“Yes, Daisy is my ex-girlfriend,” he admitted, his voice barely above a whisper. “And Patrick is my son.”
The words hit like a wrecking ball.
“You lied to me,” I said. “You looked me in the eyes and lied. You allowed me to set up the guest room, to turn my home office into a makeshift kid’s room? You watched all of that, and you didn’t think about telling me the truth?”

“I didn’t know how to tell you, Becca,” he stammered. “It was years before we met. Daisy and I broke up before Patrick was born. I’ve always supported him financially, but I kept my distance. When Daisy reached out, she said that she needed help. And I felt obligated. That’s my son, after all.”
“Obligated?” I spat. “You lied to me about who they are! You let me believe they were your cousin and nephew! Do you have any idea how humiliating this is?”
“I know,” he said, tears pooling in his eyes. “But I was scared. I thought it would push you away. I thought it would be easier this way. I’m sorry. I’ll tell Daisy and Patrick to leave tonight if that’s what you want.”

An upset woman | Source: Midjourney
His desperation might’ve softened me on any other day, but right then, it only made me angrier.
“They should’ve left the moment this charade started. You’ve disrespected me in every way possible.”
He didn’t try to argue.
“You’re right,” he whispered. “I’ll fix this.”
The next few days were excruciating.

An upset man | Source: Midjourney
Daisy avoided me entirely, and Patrick kept to his room, his usual chaos replaced by an eerie silence.
Derek threw himself into damage control, arranging for Daisy and Patrick to move into a rental while simultaneously begging for my forgiveness.
I confronted Daisy once, though.
“Why would you go along with this lie?” I demanded, watching her make her way through my kitchen while she made a sandwich.

She flushed with shame, almost dropping the jar of mayonnaise.
“I didn’t want to lie,” she said softly. “But Derek thought it would be easier. I’m sorry. I never wanted to cause problems.”
Her apology didn’t heal the wound, but it clarified one thing for me:
This disaster was Derek’s making.

Once Daisy and Patrick moved out, the house felt unbearably quiet.
Derek tried everything to make amends. He left me notes apologizing for his lies, attended therapy on his own, and took on every household chore without being asked.
His remorse was evident, but my trust in him had been shattered.

It took weeks of reflection, long conversations with my best friend, Sharon, and more than a few sleepless nights before I made my decision.
“Just know what you’re getting into, Becca,” Sharon said, stirring her matcha latte. “I’ll support you, of course, but please, think about it from all sides.”
One evening, I called Derek into the living room. He sat across from me, his face tense with anticipation.

“I’m not ready to forgive you, D,” I began, my voice steady. “But I’m willing to try.”
Relief washed over his face, but I held up a hand.
“This is your last chance, Derek,” I said firmly. “No more lies. No more half-truths. If you want this marriage to survive, you have to earn back my trust.”
“I will,” he said, his voice thick and heavy. “I promise.”

A woman sitting on a couch | Source: Midjourney
Rebuilding our marriage won’t be easy, and part of me wonders if it’s even possible.
But for now, I’m taking it one day at a time. I’ve learned one thing through all of this. Trust isn’t something you can take for granted.
It’s fragile.
As for Derek? He’s on thin ice. And if he thinks I’ll ignore the warning signs ever again, he’s dead wrong.
So now, I have to figure out how to be a stepmother.
