I cheated

I know I’m a horrible fracking person and I don’t want to hear that here I already know.

So me and my boyfriend have been dating for 4 months and idk something’s making me keep dating him but I’ve been hung up on an old hookup . Anyway I was drinking at my friends house and this old hookup guy who to explain the story better me and him have known each other since kindergarten we are and have previously been really good friends we just hooked up once a year ago. Anyway the guy was like hey want me to walk you home cause I’m right near their house anyway so I’m like fuck it and I say yes and we instead just walked around for a couple hours and ended up going back to his but the original intentions were just to hangout and shit cause are friends but we ended up having sex and idk I don’t regret I just idk. I’m 16 my boyfriends 17 and the other guys 19.
