<human>: Summarize the given text in a few sentences.

I've been dating a girl for 2 years and we have lived together for one. Last month she went out to a bar alone to meet up with some high school friends and I stayed in because I had work in the morning. I couldn't sleep though and called her around midnight and asked if she needed a ride home. She responded that she was fine and her friends were going to take her home. She seemed a little mad and I dropped it, figuring I was being an overbearing boyfriend. 

She came home later that night and fell right asleep. We didn't see each other much for the next week which isn't
unusual since our work schedules are opposites and we're both full time students. She acted distant towards me when we were together and stopped me whenever I tried to initiate anything sexual. I finally asked her what wrong and she admitted to me that the night she went out to the bars with her friends her ex boyfriend was there. 

I knew of this ex, she had had a very emotional relationship with him in the past and talked about him occasionally. She claimed that she didn't know he was going to be there that night but they had begun talking and ended up in his car. She says that she had kissed him and then he had forced himself on her and raped her. I believe her about this, I truly believe that "no means no" and that this isn't a case of consensual sex that is being called rape to justify cheating. I've accompanied her to meetings with psychiatrists and counselors and watched her tell her parents what happened. She seems truly regretful that it happened. She also does not want to go to the police, by the time she told me there was no physical evidence and she feels like a court case would be a waste of time. 

Throughout this whole ordeal I've been equal parts numb and furious. I hate that she let herself make out with an ex alone in a car. I don't know how she expected that to end. I don't blame her for being raped though, no one deserves that. I don't know if I can continue this relationship but I don't want to hurt her anymore when she's already so low.
<bot>: My gf was raped by her ex after making out with him in his car. I don't know if I can trust her anymore but I don't want to cause her even more pain.
