Girl Trouble, what do I do at this point?

Why don't you just talk to her about it. Tell her things got a bit out of control and you were both under the influence and you did some stupid things but that you want to put that behind you and remain friends and see what she says. If you want to remain friends and can handle that this is all it's going to be then do it. If you don't think you can remain friends then let it go.
