What should I do

This is a long post so please read it all...................

Anyways so about a year ago me and my boyfriend took a little break Bc he was constantly in and out of juvie and decided to go to a youth challenge program. Well when he left I told him we need to take a real until I see he's changed. During those months, while he was away, I hung out with many people; some were his friends and stuff. Well one night I was with his friend and I wanted to have sex with him and told him I wanted to but then when it came time to do it I said no I don't want to, and well he didn't listen and yea I'm pretty sure you can assume what happened. Anyways fast forward to now, my boyfriend is angry with me because he's believing that his friend is telling the truth about me begging him and telling everyone I've had sex with multiple people. He won't believe me and is making me feel like it's my fault his so called friend forced himself on me. His exact words were "you wanted it he didn't f*cking rape you Bethany him and jarred took turns!" Like no? Excuse you i never had sex with a guy named jarred. Idk why he's freaking out about it now he doesn't trust me at all he's calling me a liar and everything like that. He's making feel worthless and trying to feel like he's the victim , yea well guess what I want him to get raped and see how he feels. I wanna see him be strong and not tell anyone and try to move on like nothing happened. I'm still not okay but I'm trying so hard to be and him doing this jut brings back flashbacks and hurtful memories that make me cry. I had to leave work early because every guy I saw I saw the guy who raped me. I just don't know what to do about this relationship like I understand he's hurt and Doesnt know what to believe but damn it I'm hurt too ad he should trust me but he doesn't. He was in and out of juvie for the past two years and guess who's still here for him even when his parents gave up? Me I was here like why is he questioning everything now. I just don't know what to do about this relationship anymore.

P.S I'm sorry for any spelling/grammar mistakes; I didn't go back and check lol
