My Daughter and the Neighbor’s Daughter Look like Sisters – I Thought My Husband Was Cheating, but the Truth Was Much Worse

There they were, Emma and Lily, twirling in our backyard like twin sunflowers chasing the light. Their laughter rang out, a perfect harmony that should’ve warmed my heart. Instead, it sent a chill down my spine.

I squinted, trying to spot a difference — any difference — between my daughter and our new neighbor’s kid. But it was like looking at two copies of the same photograph. Same golden curls catching the sunlight, the same button nose, and the same mischievous glint in their eyes.

The only obvious way I could tell my Emma from Lily was the inch or so height difference between them.

“Heather?” Jack’s voice snapped me out of my trance. “You okay? You look like you’ve seen a ghost.”

I forced a smile as I glanced back at my husband. “Just thinking.”

About how our perfect little world might be built on quicksand, I didn’t add.

Jack gave me a puzzled look, but then Emma ran over and grabbed his hand.

“Come push Lily and me on the swing, Dad!” she cried.

“Uh… sure, sweetie.” His smile didn’t reach his eyes as he let Emma lead him over to the swing, where Lily was already waiting.

“Can I go first, pleeease?” Lily asked.

“Okay, but then it’s Emma’s turn,” Jack replied.

As he helped Lily onto the swing, I couldn’t help but notice how natural they looked together. Like father and daughter. The thought made my stomach churn.

Later that night, after tucking Emma in, I found myself staring at old photo albums. I flipped through pages of Emma’s baby pictures, searching for some feature that screamed “Jack’s genes.”

“What are you doing?” Jack’s voice made me jump.

He stood in the doorway, confusion etched on his face.

I snapped the album shut. “Nothing. Just… reminiscing.”

“Reminiscing…” he repeated, frowning slightly as he glanced over my shoulder at the photo album on my lap.

I could see the questions in his eyes. Questions he didn’t ask. Just like I didn’t ask about the growing distance between us, or why he always changed the subject when I mentioned our new neighbors.

Days turned into weeks, and my suspicions grew like weeds in a neglected garden. Every shared laugh between Jack and Lily, and every nervous glance when I mentioned the neighbors. It all fed the gnawing doubt in my gut.

One sleepless night, I couldn’t take it anymore. I rolled over in bed, facing Jack.

“Is Lily your daughter?” I blurted out.

The words hung in the air like smoke, acrid and suffocating. Jack’s body went rigid.

“What?” He turned slowly, his face a mask of shock. “Heather, what are you talking about? Where does this come from?”

“Don’t play dumb, Jack. The girls are identical. And you’ve been acting weird ever since Lily and her family moved in.” My voice cracked. “Just tell me the truth. Did you have an affair?”

Jack sat up, running a hand through his hair. “This is insane. Of course, I didn’t have an affair! I made a promise to you before God. How can you think I would break that?”

“Then why won’t you talk about them? Why do you clam up every time I mention Lily?”

He hung his head. His silence spoke volumes. I could almost hear the gears turning in his head, weighing truths and lies.

“I can’t… I can’t talk about this right now,” he finally muttered, swinging his legs off the bed.

“Jack, don’t you dare walk away from me!”

But he was already out the door, leaving me alone with my thoughts and fears.

The next morning, I woke up to an empty bed and a note on the nightstand. “Gone to work early. We’ll talk tonight.”

Classic Jack, avoiding confrontation.

I spent the day in a fog, going through the motions of normalcy while my mind raced. By afternoon, I couldn’t stand it anymore. I needed answers, and I knew just where to get them.

“Emma, sweetie,” I called out. “Why don’t you go play with Lily for a bit?”

Emma eagerly ran off out the door. I waited an hour before I followed, my heart pounding. I knocked on the neighbor’s door, plastering on my best “neighborhood mom” smile.

Lily’s father answered, his easy grin faltering slightly when he saw me. “Hey, it’s Heather, right? It’s so good to finally meet you! Please, come in. I’m Ryan. Emma’s out back with Lily if you’re looking for her.”

“I am… could you call her, please?”

The moment Ryan’s back was turned, I started searching through his living room.

There were numerous framed photos of Ryan and Lily with people who generally shared Ryan’s dark hair and olive skin tones. His family, I guessed. But why were there no photos of Lily’s mom?

Come to think of it, why had I never seen Lily’s mom?

I peeked down the hallway. That’s when a large photo of a blonde woman hanging on the wall upstairs caught my eye. Without thinking, I hurried up the stairs.

“What are you doing?”

I turned and spotted Ryan frowning up at me. A million excuses whirled through my mind, but they all caught in my throat. I had to find out the truth.

“Is that Lily’s mom? Where is she?”

Ryan flinched. “Yeah… that’s Mary. She’s no longer with us.”

“Because of Jack?” I trotted down the stairs. “They had an affair, didn’t they? And that’s why Lily and Emma look so much alike, isn’t it?”

Ryan’s eyes went wide with horror and he shook his head. “God, no. Didn’t Jack tell you anything?”

“No! He didn’t,” I exclaimed. “But you seem to know exactly what’s going on here, so please, just tell me!”

“Mommy?”

Lily and Emma were standing at the end of the hall, worried looks on their near-identical faces.

“Everything’s okay, girls.” Ryan smiled at them. “Me and Heather are going to talk a bit so why don’t you guys go back outside and carry on playing?”

I nodded to Emma. “I’ll call you in a little while.”

The girls exchanged a wary look but didn’t argue.

“Come, sit down.” Ryan beckoned to me as he walked into the living room. “I’ll tell you everything, Heather.”

“First of all, Jack and Mary didn’t have an affair,” Ryan said as we sat across from each other. “The reason Lily and Emma look alike is because they both take after their grandmother. My Mary was Jack’s sister.”

“Sister?” I shook my head. “Jack never mentioned having a sister.”

“Mary was a troubled kid. The family disowned her. They didn’t even come to our wedding. Jack was the only one who even took the time to send a message saying he wouldn’t be attending.”

The room spun as Ryan’s words sank in. Jack had a sister I never knew about. A sister who was Lily’s mother.

“Where is she now?”

“She passed away last year,” Ryan murmured. “That’s why we moved here. I wanted Lily to have some connection to her mom’s family.”

I put my head in my hands. Everything I thought I knew about my life, about Jack, was crumbling around me.

“I’m so sorry,” Ryan continued. “I thought you knew. Jack… he’s been struggling with this. He feels guilty about not reconnecting with Mary before she died.”

I nodded numbly, my mind reeling. Jack came from a conservative family and I knew they’d had some arguments in the past, but nothing like this!

A familiar sound caught my attention. I looked up just in time to spot Jack’s car driving into our garage next door.

“I… I need to go. Please, keep Emma here a while longer?”

Ryan had followed my gaze, but now he nodded. “Sure. You and Jack have a lot to talk about. She can stay here as long as you guys need.”

The walk home felt like miles. By the time I reached our front door, my anger had cooled, replaced by a hollow ache.

Jack was in the kitchen, staring out the window at the girls playing in Ryan’s backyard. When he turned to me, his eyes were red-rimmed.
