Requested by fatima_holland_: Peter cheats on Y/N with MJ and she finds out, leading Peter to try and apologise.

I stood at my locker, my phone in my hand as I waited for Peter to come and meet me so that we could go out to the movies for one of our movie dates. The issue was that he wasn't answering any of my texts. Peter and I had been going out for a year now, and up until about a month ago, things had been perfect. We'd have regular dates together, whether they included studying, a movie or something more intimate, and we talked every night over text and on the phone. It had been your perfect high-school relationship, with Peter always making me feel love and cherished as I slowly fell for him more by the day. But then about a month ago, things had started to change, and I still had no idea why. Peter had started to become more distant in all aspects of our relationship. He'd take longer to answer my texts and calls, he'd make less effort to arrange our dates, he even seemed to want to have less sex when we got the chance. I was hoping that it was just in my head, but now I'd been waiting for ten minutes by my locker, the halls were almost fully empty, and Peter still hadn't responded to my texts asking where he was. Something was definitely up, I just didn't know what that was. I looked up as I heard footsteps and saw Betty walking towards me.

"Hey, Betty, do you know where Peter is? He was meant to meet me here ten minutes ago." I chuckled as I tried to act like nothing was wrong. Her eyebrows furrowed as she slowed down to talk to me.

"Huh. That's weird because I overheard him inviting MJ over to his after school, and he was definitely talking about today because I saw them leave together about fifteen minutes ago." She stated. I returned her expression as my eyebrows furrowed too.

"And, what, she accepted? And neither of them mentioned that Peter and I are supposed to be on a date right now?" I scoffed.

"She happily accepted, and nope, there was no mention of your date." She shook her head. I gulped and nodded, my heart starting to race and my stomach starting to flip as I got the worst feeling in the world. The worst feeling that told me that maybe MJ and Peter hanging out at his, especially when he was meant to be on a date with me, wasn't as innocent as it seemed. I didn't want to think that negatively about my boyfriend and best friend, but right now, my mind was only going to one place.

"O-okay. Thanks for letting me know, Betty." I nodded.

"Y/N, is everything okay?" She asked as I started to walk towards the school doors.

"Yeah, I'm sure that it's nothing, see you tomorrow." I lied with a smile, making her give me a small one in return as I turned and headed out of school.

My heart sat in my throat, the feeling almost choking me as I headed along Peter's hallway to his apartment. The walk from school to Peter's apartment was twenty minutes, giving me twenty minutes to come up with a completely reasonable explanation as to why my boyfriend had ditched me to hang out instead with our best friend, without even telling me, and yet I hadn't been able to come up with one. My mind had only reached one conclusion, and I was hoping to any god out there that I was wrong. I heard MJ laughing as I reached the door, making my eyes waver as I got to the entrance. I gulped harshly, my stomach uncontrollably flipping as I took a deep breath. This was it. I was about to find out if my boyfriend was cheating on me with my best friend. I threw the door open, determined not to give them the warning of me knocking and therefore give them enough time to stop whatever they were doing. The plan worked, but it broke my heart. Peter and MJ broke the kiss and looked at me, both of their eyes widening as they saw me.

"Y/N, oh my god, fuck, fuck." Peter gulped as they jumped to opposite ends of the sofa. But it was too late. I had already seen them.

"What the fuck is going on here?" I choked, my eyes wavering and tears immediately leaving them as my heart plummeted to my feet. I had been right, and that was already killing me inside.

"I swear that it's not what it looks like, baby, please." He gulped again as he stood up and rushed to me.

"Don't you fucking touch me!" I cried and shook my head as I pulled my hand out of his grip before he could fully take it. He choked at my reaction, a tear leaving his own eye as I looked at MJ. My best friend was just sitting on the sofa, her eyes wide and her mouth hanging open as she clearly also tried to figure out what to say. Though all three of us knew that neither of them could say anything to make this okay.

"Go on, then. What fucking bullshit are you going to feed me to try and get yourselves out of this? Because I'd love to fucking hear it!" I laughed and shook my head as tears streamed down my face. Peter gulped harshly and looked down, a piercing silence taking over the room as they failed to give me answers.

"Y/N, I'm really sorry. We just...it just happened." MJ gulped and shook her head. I choked and looked at her.

"Fuck you. Fuck you both." I spat before turning and rushing out of the apartment.

"Y/N, please!" I heard Peter call after me, but I ignored him as I rushed down the hallway, my heart fucking shattered and tears streaming down my face as I rushed to get away from the pair of them.

I walked into school, deep purple bags underneath my eyes and nothing but numbness having a hold on my body as I slumped into the building. Everything sounded like it was underwater, though also sounded like it was right next to me at the same time. I felt like I wasn't me, but I knew what was to blame for that. Or rather, who. Last night, I had gone over to Peter's after he'd failed to show up for our date, only to find him kissing MJ on his sofa. My boyfriend kissing my best friend. The thought had had me in tears ever since, especially the fact that I'd never be able to unsee that. I'd never be able to unsee his hand on her cheek, his lips pressed to hers like they'd been pressed to mine a thousand times before. Except for that there was love in their kiss that had been lacking in ours for a month now. That was what hurt the most. I could pinpoint the exact moment when Peter had started to fall out of love with me and in love with MJ, because that was when he'd started acting distant. But instead of doing the actually decent thing and breaking up with me, he'd tried to let us drift apart whilst assumedly fucking my best friend. All of it fucking hurt. I looked down as my phone buzzed again, showing yet another unanswered message from Peter.

Peter: Please, baby, it's not what you think, please.

Peter: I swear to god, I love you, Y/N, please let me make this right.

Peter: Please talk to me, we need to talk about this.

I scoffed and shook my head, more tears leaving my eyes as I opened my locker and shoved the stuff that I wouldn't need for first period into it. First period that I really wanted to skip because both Peter and MJ were in that class with me. Fuck my life.

"Y/N." I gulped harshly, my heart leaping as I heard Peter's voice. I clenched my jaw and blatantly ignored him as I felt his presence appear beside me.

"Leave me alone, Peter." I mumbled.

"We need to talk, please, baby-."

"No. Peter. You do not get to call me that after I caught you cheating on me with my best fucking friend." I spat as I turned to face him. He gulped harshly and timidly looked around.

"Please. Give me five minutes-."

"Fuck you." I choked before slamming my locker shut and turning to leave. My eyes widened, a quiet yelp leaving my lips as Peter grabbed my bicep and started to pull me towards an empty classroom.

"Get the fuck off of me, let me go." I choked as he pulled me into the classroom before shutting the door.

"Not until you let me explain-."

"Peter, do you not get it, there's nothing to explain! I caught you kissing my best friend, so I don't want to hear your fucking half-assed excuse for an apology that you don't mean!" I yelled as fresh tears started to leave my eyes again.

"Please just let me speak." He choked. I looked at him, my throat gulping harshly as tears also ran down his face. I knew that he didn't deserve a chance to chat his way out of this, and we both knew that he'd not be able to. But part of me wanted to know how he was going to explain it. How he was going to explain breaking my fucking heart.

"You get one minute before I walk out of here and never speak to you or MJ again." I nodded, making him look at me. He sighed and gulped.

"First of all, I just want to say how sorry I am. I know that you're not going to accept it and that's completely fine, but I wanted you to know that. As for MJ and I, it just...happened. She was hanging out at mine one day, we were studying, you knew about it. I-I started to confide in her about the fact that I felt like we were drifting apart, that the more our relationship progressed, the less that I saw you as my girlfriend and the more that I saw you as a friend. A-and...the less that I saw her as a friend, and the more that I wanted her to be my girlfriend." he started. My eyes wavered, every word already slashing through my heart like a knife as I tried to listen without walking out of there. Not that he deserved another second of my life.

"S-so, she ended up kissing me. And I kissed back. We both realised very quickly what we'd done and how fucked up it was that we'd both betrayed you. So, I agreed to break up with you to be with MJ. I want to make it clear that she didn't make me end it with you o-or pressure me to. I'm so sorry, Y/N, but I had wanted to end things for a bit by that time, and so MJ liking me back was just more incentive to do that." He nodded.

"Okay, but that would have been fine IF you'd had fucking done it. Sure, I would have been hurt by you breaking up with me, especially for my best friend, but I can promise you that I'd not have been as fucking hurt as I am right now." I sobbed and shook my head. Peter gulped and looked at me, his eyes also red as the asshole cried too. As if he had a right to.

"I know. I was planning to do it, but every time that I tried, I just couldn't. Every time that I set out to do it, we ended up having an amazing date, or we ended up having sex, or you'd look at me in a particular way that made me just not want to do it. I couldn't do it." He choked.

"And so you continued to play me for a month. You honestly thought that the best way to break up with me whilst fucking my best friend was to distance yourself, or whatever the fuck you've been doing for the last four weeks. Now I know why you didn't want sex, or why it took longer to respond to me, you were doing all of that shit with MJ." I cried.

"And I can never be sorry enough for that-."

"No, Peter, you don't get to fucking clear your conscience by apologising to me. What you've done is worse than anything that my worst enemy could have ever done to me. Not only did you cheat on me, not only did you betray me, but you did it with my best friend. You did it with MJ. So, not only am I left with a broken heart and no boyfriend, but I also just lost my best friend too. You fucking took everything from me." I nodded, my head starting to thump with how much I was crying.

"It was never the plan for you to get this hurt-."

"And yet that's what fucking happened. Despite your best efforts to be a saviour and sneak around behind my back so that you wouldn't hurt me, I found out. I fucking found out, and now the damage that you've done is irreversible." I choked. Peter returned it, both of us just staring at each other with red eyes. I looked down and took a deep breath, my heart feeling utterly numb as I desperately tried to process everything. Because there was a fucking lot. I was now single, had just lost my best friend and was also left with a broken heart, with the two people who would usually fix it for me being the ones who had made that happen. I didn't know what to think, I didn't know what to feel, apart from completely betrayed. And nothing was going to make this okay. It would never be okay again.

"We're done, Peter. I'm pretty sure that that was obvious by now, but just in case you were thinking with the same brain that said that it was better to cheat on me than to break up with me, we're done." I choked as I looked back up at him.

"Y/N, please." He whispered. I bit my lip so harshly that I tasted blood as I shook my head.

"Stop trying to make this okay, because it's never going to be okay. We're never going to come back from this, as a couple, or as friends. Both you and MJ leave me alone from now on. I can never trust either of you again, and so everything is over. Us as a couple is over, us as best friends is over, and MJ and I are over. It's done." I nodded, my entire body feeling numb as I went back to the door and opened it.

"Please-." I ignored him again, my chest feeling empty as I left the classroom and headed towards the school doors. I couldn't be here, I couldn't be in class with my ex-boyfriend and ex-best friend who had helped each other to break my heart. Neither of them would be able to make this okay, and we all knew it. We all knew that they'd done damage beyond repair. And now, I was the one who had to live with that. And live with that, without them.
