I walked around Tom and mine's house, hands against my increasingly growing pregnancy bump as I smiled and greeted everyone who had come to our gender reveal party. I smiled at Tom as he walked up to me, his arms wrapping around my waist as he looked at me. 

"Everyone is here and having a good time, I think that we should cut the cake soon, yeah? I want to know if we're having a boy or a girl." He smiled. 

"So do I, babe, but we'll find out regardless, the baby's sex isn't going to change in five minutes." I chuckled. 

"I want to know, though." He fake-whined, making me smile and shake my head as I took his face and gently pressed our lips together. Tom smiled into it, holding my waist as he returned the kiss. 

"Ahem." We broke the kiss and looked to the side to see Harrison now next to us. The boy looked at me. 

"Y/N, can I borrow you for a second?" he asked. My eyebrows furrowed, as did Tom's as we looked at each other. 

"I'm sure that it can wait, Harrison-." 

"It really can't." he shook his head as he clenched his jaw and stared at me. My eyes widened, this being the first time that I'd ever seen such aggression in Harrison's eyes. I gulped and hesitantly nodded as I looked at Tom. 

"Don't cut the cake without me, okay?" I chuckled as I leant up and kissed him again. 

"Like I would." He returned. I smiled and bit my lip, the smile immediately dipping as Harrison grabbed my bicep and started to drag me into the bathroom, away from everyone else. 

"Ow, Haz, Jesus, I'm pregnant, be careful." I scoffed. 

"Oh, please, the baby isn't in your arm." He returned as he pushed me into the room and walked in behind me before locking the door. He turned to face me. 

"I know your secret." He nodded as he crossed his arms over his chest. My eyebrows furrowed at the statement. 

"What secret?" I chuckled, cupping my bump again. He squinted his eyes at me and clenched his jaw again. 

"I know that whilst YOU are having a baby, Tom isn't. Because the baby isn't his." He nodded. My eyes wavered and my heart dropped to my feet as he uttered those words. I gulped, my mouth suddenly becoming dryer than a desert, as I knew that I couldn't lie my way out of this. 

"How do you know?" I mumbled quietly. Harrison sighed and shook his head, his jaw still clenched.

"I'm friends with the guy that you had sex with, luckily, Tom isn't. He told me that you two hooked up just after Tom left for LA and that he only did it because he thought that you and Tom had broken up, which apparently you didn't deny. I was going to say something to Tom as soon as I got told, but then you turned up pregnant. I thought that surely, you'd tell him then, you wouldn't let him raise a child that wasn't his. But no. You still haven't fucking told him. You still haven't told him and now all of his friends and family are out there, waiting to see whether you're having a boy or a girl, but with no fucking idea that they're there for a child that isn't even Tom's. How the fuck could you do this?" he spat. 

"I'm so sorry, Haz, I never meant for this to happen, I didn't mean to get pregnant." I choked. 

"Y/N, that's not the fucking point here. The point is that you slept with someone else, you cheated on Tom, and have now led him to believe that he's the father of your child. This wouldn't be an issue if the baby inside of you was his. But it's not. The cheating is the problem, Y/N, not the fucking pregnancy." He shook his head. My eyes wavered and I nodded, my gaze moving to the floor as a tear fell from my eye. 

"Y/N, you need to tell him. If Tom doesn't know by the end of this party that he isn't the father, he's going to hear it from me. Okay?" Harrison asked. 

"Yeah, Haz, I understand." I nodded, my voice quiet. He sighed and nodded, giving me one last look before turning and unlocking the door before leaving the bathroom. I bit my lip, tears pricking my eyes as I knew that by the end of the day, I would go from being pregnant and about to give myself and Tom a family, to being a single pregnant woman who was going to be a single mum in a couple of months. Though obviously, I had no one to blame but myself, I just didn't know how I'd been so stupid as to get pregnant. Fuck, I didn't know how I'd been so stupid as to risk my relationship with Tom over what had turned out to be a stupid fling. At any rate, it was too late now. I took a shaky breath out, my hands protectively cupping my bump as I left the bathroom and went back out to the party. 

"Can I have everyone's attention, please?" Tom yelled, making everyone look at us as someone clicked the music off. I gulped, Harrison's stare on me. My eyes wavered as I looked up at Tom. 

"Tommy, wait, I need to talk to you privately for a moment." I nodded. 

"It can wait for a minute, darling." He chuckled. 

"No, Tom, it can't-." 

"Come on, you two, I want to know if I'm getting a niece or a nephew." Harrison spoke, making everyone cheer and agree. I clenched my jaw at Harrison, a tear leaving my eye as his gaze remained cold. 

"Everyone ready?" Tom asked as he held up the knife. 

"Do it!" Sam shouted, making everyone cheer. 

"Okay, okay. Here we go." Tom chuckled as he lowered the knife. He cut into the cake and pulled the slice out, making everyone gasp and cheer as the pink sponge was revealed. 

"It's a girl!" Harry declared as everyone cheered and clapped. 

"We're having a daughter, sweetheart, isn't that amazing!" Tom laughed as he hugged me. I gulped and bit my lip, a tear leaving my eye at what I was about to say. 

"No. We're not having a daughter. I'm having a daughter." I spoke into his ear. Tom pulled away from me slightly, looking at me with furrowed eyebrows as he held his arms around my waist. 

"What do you mean?" he chuckled. I bit my lip so hard that I could taste blood as the noise in the room started to die down so that our words could be heard. 

"Tommy, I'm so sorry." I choked and shook my head. Tom's smile dipped further, and he took a step back, making me wince as he completely removed his arms from me. 

"Y/N, what's going on? What are you talking about, we're not having a daughter?" he scoffed and shook his head. I gulped, my heart in my throat as I forced myself to look into his stunning hazel eyes. 

"The baby isn't yours, Tom." I admitted. His eyes widened, gasps filling the room as everyone listened. 

"Y/N, stop, this isn't funny." He shook his head. 

"And it's not a joke. I'm so sorry." I choked. Tom stared at me, his eyes filling with tears as he clenched his jaw. 

"I want to hear you say it. I want you to say what you did." He nodded. My eyes wavered. 

"Tommy, all of our friends and family are here, let's go somewhere private-." 

"No, Y/N, the time for that is well gone. You're seven months pregnant, that means that I've believed for seven fucking months that I was going to be a dad. And yet you choose the gender reveal party, in my house, for a baby that isn't even mine, to tell me? That not only have you fucking cheated on me but that you also led me to believe that I was going to be a dad?" he choked and shook his head. 

"I know, Tom, there's nothing right about what I've done, or how I've handled it. I'm so sorry." I cried. He shrugged and shook his head, his eyes wavering and a tear falling from his eye as he looked around at everyone. 

"The party's over, everyone. On behalf of myself and my now-ex-girlfriend, I am so sorry that you spent money on gifts for someone else's baby and that you rearranged stuff to be here and that some of you travelled quite a way, just to learn that I'm not actually going to be a dad. Thank you all for coming." Tom nodded, giving me one last look before shooting up the stairs and out of sight. I choked, tears rapidly falling down my face as everyone looked at me. 

"You heard him, folks. Clear out, I'm sure that Tom just wants to be alone now." Harrison nodded, people returning it as they grabbed their stuff and started to leave. Harrison turned to me. 

"As for you, I suggest that you grab a bag and you leave too." He spoke. I gulped and nodded, my eyes wavering as I grabbed my purse and left the house too. I got into my car, my shaking hands finding the steering wheel as I just sat there. Tears silently ran down my face, my brain still trying to process what had just happened. Not that I wasn't to blame for every single part of it. I choked and looked down, holding my bump protectively as I looked at it. I would kill for this baby to be Tom's, but the fact was that it wasn't. And I couldn't change that, no matter what I did. I sniffed, wiping my eyes as I started my car and started to drive along the street, slowly but surely driving out of Tom's life.
