I wouldn't put all the owness on her. There's a good chance she was interested in him romantically and a straight guy (wich is what he lead her to believe he was) taking a girl about town and bringing her home to meet his "buddy" (wich is what you were portraid as) without putting the moves on her would make her feel that there was the potential of a serious romantic relationship rather than just a physical. Just as everyone said if he wants to be out, that's his buisiness, but the same goes for you. If you're out then your out and he shouldn't force you into the closet for his friends anymore than you can force him out of it.
