Search Results: he cried when he broke it off

So my girlfriend went to a party where there was a lot of drink and she got pretty drunk. There was a lot of people at the party that I knew, both male and female so several of them have told me exactly what happened.

Apparently, towards the end of the night she sat on another girl's lap and they started kissing. It soon turned into them making out, as a bunch of people started cheering them on. They also had their hands all over each other and the other girl took my girlfriend off to a bedroom.

After confronting my girlfriend about it, she has admitted it but claims they were too drunk to do anything and that they only heavy petted each other through clothing, although I kept going on at her about it and she also admitted to giving the girl oral and the girl touching her down below, under her panties. But she then took that back and said nothing happened at all besides kissing and touching through clothes. And she keeps insisting that they were too drunk to do much and ended up passing out. She says she doesn't remember most of it.

She is upset and has been crying and insists that she didn't know what she was properly doing, because of the alcohol, and that she regrets it. She has apologised multiple times and tells me that she loves me and isn't interested in women, but I don't know what to believe now. I'm not sure what to do?
