One of my best friends had fancied this guy for quite a while now and a few nights ago, something happened between them (not sure what). He has a girlfriend, although she's away at uni. I would say my friend is fairly inexperienced with guys so whatever happened I think it was quite a big deal for her, but he is obviously not interested and it was quite drunken. However I think she wishes that it wasn't just a one-off, and she has told him this. What is really bad is that they were great friends before and now I don't know how it will work out, and I am friends wih both of them and am a bit stuck in the middle. I feel I should side with the girl since she is younger, less experienced and probably a bit desparate, also he has a girlfriend and should have known what he was doing was worng. But on the other hand I guess she was pretty dumb to get herself in this situation, and to be honest i don't know, and i don't think they really know who started it.
Please help, I just don't know what to do.
