<human>: I discovered my girlfriend was (only emotionally - allegedly) cheating on me for months. I confronted her, lots of tears and talking, she seemed legitimately sorry, etc etc... I tried to forgive her and we tried to move on, but more lies surfaced - no big ones, but enough for me to give up on her.

We have a close, shared circle of friends. The question is now: should I just say we separated, or should I also mention her betrayal? Part of me still loves her, cares a lot about her and thinks she should learn to be honest and tell herself when people ask - punishing her won't help things, another part of me just wants revenge and thinks that she brought it on herself and that she deserves her reputation to burn down to ground. I've never been in this position before and I honestly don't know the "right" thing to do. I feel very disoriented.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Should I tell people I broke up with my girlfriend because she cheated on me, or should I just tell we broke up?
