<human>: So today I learned my girlfriend cheated early on in our relaionship. After watching an episode of the office today in which one character suspects another of cheating she looked at me and said "there's something I have to tell you". My heart stopped because I knew it could only be one thing.

About 2.5 months after we started dating/several weeks after becoming 'official', my girlfriend went on birthright to Israel. She told me while she was there a friend of hers who also went on the trip began hitting on her. She declined the advances and said she had a boyfriend. Well after having a lot to drink she stopped declining and decided to have sex with him. We were trying to stay in contact while she was in Israel through email. I still remember the only email I got from her that day was "Israelis sure know how to party".

When she told me today she seemed racked with guilt. She blamed the alcohol but I know that's bullshit and she eventually admitted that too. I told her I'd be stupid to stay after her cheating on me and lying to me for the last 7 months. She also broke up with me shortly after returning from this trip because according to her today she felt so ashamed, though at the time she said it was because we were at different points in our life (I'm out of college, she's still in school). She begged to get back together and of course I took her back. She hasn't been in contact with this guy since the trip but he goes to the same school she goes to.

My question I guess is it possible to forgive her or get past this? My heart wants to stay with her because I truly love her but my brain says I'd be foolish to give her another chance. For now I told her not to contact me until she talks to a therapist.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Girlfriend cheated early on in our relationship while on birthright to Israel. She confessed today and I have no idea whether I should stay with her or not.
