<human>: /r/relationship_advice x-post.

My boyfriend revealed to me a few nights ago that he cheated one night when we first started dating back in May. We'd been sleeping together casually a few months prior, but there was no one else involved on either end. He was in tears the entire time he told me about it, saying that I deserve better and he'd understand if I left. I let it slide, and have no intentions of leaving. He swore that it wouldn't happen again and I truly want to believe him but I just can't get myself over it. I want to move past this and be happy with him but we've talked about how it upsets me every night since then. He's offered to show me his texts and social media messages, but I know that they won't help me get past this. Part of the reason that it's got me so worked up is that we've been essentially living together since we started dating and I hate the thought that he was with someone and then slept with me in my bed a few nights afterwards. I just don't know how to forgive/trust him again.

Give me a shortened version of the text
<bot>: I don't want to break up with my boyfriend, though he cheated. I just don't know how to get over it.
