M💋

You don't know what exactly you were thinking about, it was more like your thoughts racing over others about all the memories, all the things he’d done that made sense he’d been cheating.

You almost forgot you were on Mikasa’s couch; if she hadn't put her hand on your shoulder, you would've been seconds away from a panic attack.

This had to be a dream, right? It's just a realistic nightmare that you've yet to wake up from. Except, you know it's real. And it's all crashing down on you. You don't know what to feel, what to think, or how long this has been going on for?

It can't be your eren, no. That's impossible. The same man you've been with since the sophomore year of high school, the same man you've shared all your firsts with, the man who said it was you and only you he wanted in his life, the same man who said he kisses the ground you walk on.

You’d been thinking every possible thought in a second, and from your perspective, it's felt like years already. You hear Mikasa trying to drag out what happened, urging you to tell her. But you just can't. You're scared that if you speak, you’d be even more of a mess than you already are. But maybe that's what you need. You can't be with a man who can't stay loyal, when you've done everything to be. You need to let it out to start to move on. Unless…

“—-n? y/n! Are you okay? You spaced out again. What did eren do? Who is it?”

You heard Mikasa ask, processing how to even start explaining how you'd even found out, all of this being an hour ago. Thinking about the situation from start to finish made your head pound harder. But you needed to get it out, to scream, cry, anything and everything.

“Her name is Bri. That bitches name is Bri.”

It wasn't easy to declare that, as it’d solidify the fact that Eren had been fooling around with another woman while he comes home to you kissing your cheek and saying sweet nothings in your ear while expressing his desire to have a child of his own with you. God, how much worse had it been right now if you had been married to him? You realize how big a bullet you dodged by not being married to him, and having his children.

How goddamn easy was it for him to fuck another woman, and come back home to your girlfriend and act as if it was an ordinary routine, like it was normal? It blew your mind, not that you wouldn't mind if that actually happened. You felt shame and anger, and how could you have been so blind? But you snapped put of that, you couldn't have known, it wasn't your fault. It never was.

You gave your all, your love, time, and heart, that was more than enough to prove you wanted to settle down with him for an eternity. That would've been enough to prove you were ready to perish with him if needed.

You squint your eyes staring at your reflection from Mikasa’s tv, you were barely in your 20’s. You were ethereal, full of life, and you had a body you were more than pleased with. You needed to realize your life isn't over because you’d have found an open door out of something you never knew was keeping you from living life to its full extent.

You had never been able see the world outside of eren, to you, he was your world. You basically grew up with him. Learning that he’d fucked another girl, even forming a relationship with her while he said he only had eyes for you, and he dared to think you would've never found out, filled you with an unexplainable rage. Something you'd need to quench, or God so help us you’d rear up the city at any moment to relieve that pain. You needed revenge.

“Mikasa, how could I have not noticed this sooner. And how did he ever think I would've never found out”

The tone you gave revealed you had more rage than misery.

“He’s fucking stupid for that. But you know what, be glad you noticed now, than never y/n. Imagine if you’d married him??”

You heard her reply.

She was right. You already had thought that. But her confirming that made it clearer. You would've never been able to even see the surrounding world outside of the hole he would've dug you in if you had decided to take his last name and let him put a ring on your finger. You now felt disgust remembering how you'd fantasize about ever feeling the desire to marry him, spend the holidays at his parents', maybe even having a kid together.

You were so glad you didn't make it to that point, how much more difficult would it have been then?

“Is it wrong to say I'm kinda glad he did? I mean, I'm seeing every possible outcome that would happen if I had never found out.”

And you were right.

You felt Mikasa embrace you finally, feeling that you needed someone more than the feeling of devastation and anger, she needed to get it off your mind.

Of course, you knew Mikasa is eren's childhood best friend, but she was yours too.

You had met her before she ever met eren and their other friend armin. Nothing could get in between your bond, and that meant that now receiving the information that eren had broken one of her closest friends' trust, and heart, meant that she’d do anything to support you, and guide you through that feeling, seeing the way out of it, and being there with you on that journey.

Even she couldn't express the amount of shock, and anger she felt towards him right now. The fact that he’d been this kind of person to have done that, was just repulsive.

You and Mikasa had been hugging for more than 5 minutes now. She rubs your back and swings you guys side to side gently to soothe you while you finally let your tears drown your eyelashes and your cheeks. She so desperately wants to figure out how else to make you feel better, to lessen the pain you're feeling, but of course, that isn't possible. So she’ll do the best she can.

She slowly removes herself from the embrace, to bring her thumb up to your cheek and wipe away the tears falling down your soaked face.

Finally, Mikasa spoke.

“Let me get you a spare change of clothes and get the guest room ready for you, yeah? Or you can sleep in my bed tonight if you don't wanna be alone, whatever you want!”

She already knew how you were, you weren't able to be alone with your thoughts if you were ever going through anything that made tears fall from your eyes. And of course, she didn't mind. She knew you didn't want to be alone, and she knew herself she needed you within her sight to make sure you were alright.

“Yeah, I'll sleep with you tonight. Honestly, I can't go to work today, I'm just gonna call in sick.” you silently let out, sniffling while getting up while she walks to get you spare change of clothes and start the shower for you.

You hadn't even mentioned that you took his phone with you, not even wanting to discuss what else you could find in it. You looked long and hard at it, you couldn't even fathom the thought of how many women he’s been cheating on you with. You also decided you were gonna tell her you brought it whenever you were to wake up once you freshen up at the moment.

_________________________________________________

After calling in sick and taking a shower, you were now in spare pajamas that you had left from the previous sleepovers you've had at Mikasa’s apartment.

You stare at yourself in the bathroom mirror, wondering how it went in this direction, how HE could do that to YOU, and act like it was completely fine before you found out.

You walk out of the bathroom, not wanting to focus on it any longer, and walk to Mikasa’s room. Opening the door, you see her in bed already leaning back on a pile of pillows totally not staring at you like she wants you to tell her more about what happened, but of course, she respects your boundaries.

You hop into the ned next to her, and snuggle into her side, wrapping your arm over her mid section, and let out a deep sigh. Feeling your eyes sore from the tears, you realize you can't sulk over this forever. You need to do something about it, you need to do something about him, and get your lickback.

You feel Mikasa’s arm shift slightly upwards from under you, and feel her hand in your hair slowly and gently running her fingers through the strands, feeling the relief and warmth of a friend your mind settles slightly, giving you temporary relief from the pressure headache from the clenching of your jaw and sobbing.

You start to close your eyes, completely defeated in your emotions and exhaustion. You go over all the thoughts about Eren’s behavior leading up to this, the secret phone calls, the staying out late, and the “overtime” at his job.

It's unbelievable how someone you completely trusted and loved could do this to you. And for what? The laughter you shared, the moments experienced in your relationship. Whenever you had slight second guesses of his loyalty, he’d get so defensive and “prove” his love to you by just bringing you flowers and your favorite food, and snacks, but it never filled the growing void of the situation unfolding. It was only a matter of time you'd find out, and it was now.

You feel your eyes shut, but not before telling yourself over and over again, you oh so needed sweet sweet revenge.

And you were gonna get that no matter what.

Note: chat I'm sorry if this was all over the place, it's my first time writing an x reader or anything fanfiction for that matter 😭 but I had fun with this one and I tried to make the emotions as detailed and relatable as possible. And I may have made Mikasa a tad with ooc but in this au eren is a cheater so anything goes 👅

It's been 5 minutes since you’ve been staring at the clock on your nightstand. You’d like to enjoy your beauty sleep, but something just isn't letting you. It's currently 4:16 am. You have work in 4 hours, and it's killing you.

You glance at eren next to you, sleeping soundly, something in you is annoyed about that. Seeing him sleep peacefully always made you chuckle, but you don't know why now you want to suffocate him with your pillow.

Tick. Tick. Tick……

10 minutes went by.

You still can't sleep, and by now you're considering getting up and making your way to the living room and turning on the tv to watch yellow jackets. Anything to just occupy yourself from this odd feeling in your stomach?

As you're about to get up, you hear buzzing coming from Eren’s phone next to his head, you debate whether to wake him up since it might be one of his little friends calling him to tell him some absolute bullshit they did, but something tells you to wait it out. So you did.

After the buzzing stopped, leaving the person calling to voicemail, you get up, and you hear it again. Something is itching you, no, URGING you to find out who it is.

You've never felt the need to think eren was that kinda guy to cheat, especially when he said he’d love you every morning, and night. That's just something that can't happen, right? You'd scowl at the stories other people share in TikTok comment sections, saying to always listen to your gut when you feel something is wrong. You always thought that was a myth.

Until you piece together eren’s been taking calls in the other room, running to your shared bedroom to take it. He’d always answer them in front of you, even putting it on speaker and letting you say hello to whoever is on the line. But you brushed it off, thinking it was family matters.

You've always trusted him, right? Why is now any different?

That self reassurance left your mind when you heard buzzing again. This was the second time. It was almost like it was calling YOU to answer it.

Reluctantly you get up, tiptoeing to the other side of the bed where eren is lying, gently taking his phone, not daring to wake him up and have him ask you what you're doing and have him ask you if you don't trust your own boyfriend again. You roll your eyes thinking about that vague memory, with his phone in your hand, you quietly exit the room walking to the living room. The pit in your stomach is now doubling, like you're at Six Flags awaiting getting on the craziest ride. You start wondering if this is the right thing.

You wouldn't be with him if you didn't fully trust him, right?? Of course you wouldn't, that's why you'd do a little peek to see who's calling him at 4 in the fucking morning twice nonetheless. You sit down on the couch, with nothing to cover yourself since you're already burning up from the anticipation and the anxiety that you're experiencing from the mere thought of typing in his passcode.

You hesitate to type in the code, taking a long pause after each number. Now you're at the last one, you close your eyes tight, inhaling and exhaling a little hastily to prepare yourself. Once it opens, you see the home screen.

It's you kissing Eren’s cheek. It's a photo from high school after your guys' first date. That alone makes you do a 180 and you feel immediate guilt. But you swallow it, and click his messages. You only see his friends' texts, nothing out of the ordinary, then you check his missed calls.

Your eyebrows crease, seeing the name “bri”. You didn't know a Bri. The only women you knew were Mikasa, Sasha, and historia, and her girlfriend Ymir. Even then they didn't have anyone named Bri in their circle. You impulsively call “Bri” back, you told yourself maybe it was a guy with a mother who thought the name “Bri” was a good idea.

Ring.

Ring.

Pick up

Well that was quick.

Your thoughts are cut off when you hear “so nowww you answer hahaa”…

That's a woman. You didn't recognize her voice. Maybe it's one of his co-workers, right? Right????

“Hello? Babe?”

Your stomach dropped to your fucking uterus.

Call ended.

You ended the call.

Who was she? Why was she calling Eren “babe”? Your thoughts are now racing to this conclusion. He can't be cheating. He can't. HE pursued YOU first. HE begged for YOU.

You don't feel the need to cry. All you feel is shock, Anxiety, fear, devastation, and the need to throw up.

You can't deal with this.

You get up, going to get your car keys, but not before you get a piece of paper, and the struggle of finding a pen. And write

“YOUR WHORE BRI CALLED YOU.”

You left it on the counter, along with his phone. Or maybe you should take it? Should you? You did.

You get into your car, rushing to get the damn thing running. Once it is, you leave the driveway to go to Mikasa’s house. You call Mikasa during the process, you can't stand to sit in silence for 20 minutes on the way to her.

“Mikasa?” You say with an undertone in your voice that she's never heard.

“Y/n? What's wrong?” you can tell she just woke up too. She has a day off today so you hope she isn't too mad you're calling her so early, but you shake that off and tell her what just happened.

Moment of silence

“I think eren is cheating on me. I'm on my way to your house I can't stay in that house with him right now.”

“He’s WHAT??” You hear her scream out. You would've laughed since you've never heard her scream out like that before, but you've just discovered Pandora's box from your perspective currently.

20 minutes later.

You're on her couch staring at nothing, thinking about everything. Every opportunity you've wasted, having Eren in mind. Every dream job offer you've received, down the drain.

All to lead up to this moment.
