Requested by mrsholland199601: Y/N finds out that her boyfriend is cheating on her. And Peter finds out at the same time.

"Okay, I'll admit that that was actually a decent movie." I chuckled, looking up at Peter as we walked through the shopping mall.

"I told you so! I knew that you'd enjoy it, even if it was Star Wars." he teased as he gently nudged me with his shoulder.

"Alright, alright, Pete." I smiled and jokingly rolled my eyes before looking ahead. My eyes widened and my smile started to dip as I saw my boyfriend sitting by the water fountain, laughing with the girl who he had an arm around. Peter's eyebrows furrowed and he followed my gaze before he realised what he was seeing.

"He said that he was working today. That's why he couldn't hang out and that's why I asked you instead." I nodded.

"Y/N, fuck, I'm sorry." Peter sighed. I shook my head.

"I'm going to confront him." I decided, making Peter's eyes widen as I started to walk towards him.

"Y/N, just wait." he gulped, pulling me back as he gently took my bicep.

"Wait for what, Peter?! He's clearly on a date with this girl, and I'm not going to wait until they leave so that he can just lie to my face later about it." I scoffed. Peter opened his mouth to speak but nothing came out as he looked at them again.

"M-maybe, they're just friends." he shrugged. I looked at them, my heart dropping and my eyes wavering as my boyfriend leant in and kissed her.

"Okay, maybe not." Peter sighed as he let go of my arm. I choked and shook my head as I stormed towards them. My boyfriend broke the kiss and looked up at me as I approached them, his eyes widening.

"Y/N, Jesus-."

"You son of a bitch." I choked and shook my head, Peter reaching my side as he caught up with me.

"It isn't what it looks like, babe-."

"What is it then, asshole?" Peter stepped in, making me look up at him. My boyfriend scoffed and narrowed his eyes at him as he stood up.

"This is none of your business, Parker." he snapped.

"How the fuck is this none of my business? You've just cheated on my best friend. I'm the one who'll be left here to fix her broken heart. And of course, I'm there for that, but I shouldn't have to do that because you shouldn't be a lying piece-of-shit of a boyfriend. So tell me again that it's none of my business." he spat. I choked and shook my head as I looked at my boyfriend. He sighed.

"I'm sorry, Y/N. I didn't want you to find out this way." he gulped.

"Yeah, well, I did. And we're done." I nodded. He sighed and looked down.

"Let's go." Peter mumbled, staring my now-ex boyfriend down as he wrapped his arm around me and walked us away.

Tears ran down my face as I rushed to my apartment, Peter in close tow behind me.

"Y/N, I really think that we need to talk about what just happened." he gulped, looking at me for an answer as I forced my key into the door with shaky fingers and let us in.

"What's there to talk about? I got cheated on, I dumped him, done." I sniffed as I rushed in and threw my wardrobe doors open.

"Peter, be an amazing best friend and grab a trash bag, would you?" I asked, my eyes stinging as I grabbed all of my ex's t-shirts and clothes from the wardrobe. Peter just looked at me.

"I think that a better use of my skills would be making you talk about this. It's not healthy to bottle this up." he shook his head.

"No, what's not healthy is keeping the clothes of a guy who cheated on me." I nodded, tears running down my face as I turned around to look at him.

"Where's the trash bag?" I scoffed, though there was a choke in my voice. Peter sighed and looked at me.

"I really think that we need to talk about this." he insisted.

"I don't want to talk about it. I've just been cheated on, Pete, I need to get rid of his stuff." I nodded before my eyes wavered. Peter sighed.

"I've just been cheated on." I choked, my mind only starting now to process what had happened as I dropped the clothes and slid down the wardrobe door, to the floor. Peter looked at me, sympathy in his eyes as he walked to me. He sat down next to me and gently pulled me onto his lap. I sobbed into his shirt, the material balled into my fists as he gently cradled me.

"I'm so sorry, Y/N. I'm so sorry." he choked as he gently pressed his lips to my hair.

"I just don't understand why. What did I do so wrong?" I sobbed. Peter sighed and looked down at me as he gently rubbed one hand up and down my back whilst the other hand played with my hair.

"You're not the problem here, Y/N, he is. If he was so unhappy, he should have just broken up with you. But instead he decided to be a scumbag who cheats on his loving girlfriend. You're not the problem here, he failed to see how amazing you are, and that's on him." he cooed softly. I choked and nodded.

"I just feel so numb right now, Pete. I loved him. And that's how he repays me." I whispered.

"I know, Y/N, I know. But you'll be okay. You're a fighter, you always have been, and you've overcome more than an asshole ex-boyfriend. But even if you can't fight, I can for you. I'm not leaving your side. I'll be here for you always, I can be strong for you if you don't want to be." he reassured. I sniffed as I looked up at him, making him give me a small smile as he looked down at me.

"Thank you, Pete. I love you so much." I choked.

"I love you too, Y/N. And I'm not leaving your side." he promised. I gave him a small smile, tears still rolling down my cheeks as I rested my head against his chest again and he kissed my hair. We stayed like that for the rest of the afternoon, my hurt body being cradled in my best friend's embrace. Peter kept his word. He never left my side.
