<human>: I recently found out that this past summer my girlfriend, we'll call her Sandra was raped at a party. From what I'm told she doesn't remember a thing, she was drunk and passed out. At the time it happened we had just had a big fight, so she didn't tell me until later, and then she just told me she remembers the guy trying to get into her pants and her pushing him away.

I found out last week from Sandra, that a few months ago, a mutual friend of Sandra, (we'll call her Danielle), and the guy, told her that he had told Danielle that he and Sandra had had sex. Danielle said that the guy admits that Sandra was completely blacked out.

She didn't tell me when she found out because she was afraid of how I'd react (rightfully so I think). She still won't tell me who the guy is for the same reason. She seems completely ok with it, I don't know if she's over it, burying it, or just doesn't want to deal with the drama of the social circle. 

I should add that she was raped once before, long before I met her, I didn't push, but got the impression that there was force involved. I have no idea what to do...do I let it go and let her deal with it, or do I push and potentially make the situation ten times worse if she really is over it. It's not like there's really anything that can be done legally at this point. I'm almost afraid of finding out who it is because of what I'll do if I run into the guy.

Help?

Can you provide a brief overview of the text?
