<human>: My girlfriend of 7 months went home for the weekend (we live in dorms in college) and then told me her best friend (also ex-boyfriend) tried to kiss her. She did very well and told him no, but she says she is still friends with him and even though she said no he will probably try again because he's "a guy" and I "just need to learn to live with it". I can see a future with her, but I can't see a future with that asshole following her around for who knows how long. She wants me to forgive him but in my eyes, what he did was just as bad as cheating and that is unforgivable. She told me I can't talk to him at all which may or may not be a good thing. Over the summer, she will be home for 3 months and her only friend back home is him, so she tells me there is no way she will just tell him to leave her alone. We had about an 8 hour argument over text about this and we cane to the "agreement" that over the summer she will "hold him off" but won't tell me if he tries again. I starting to feel like this relationship is more stressful than it's worth. I love her a lot though, and I'm just very confused. What do you all think. Should I stay or let her go?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: my girlfriend has a pursuer who she thinks won't stop pursuing her and i just have to be okay with it and okay with her talking to him constantly.
