Did they actually DO anything, or not? That is the question you need answered from your GF.
I agree w/Lesa, alcohol has never made me lose complete control of myself. However, I *have* crashed so hard that I'm dead to the world until the next morning. If she woke up, startled that someone was in the bed with her, well, that's quite a bit different from knowing he was there & snugging up to him.
Your friend, however, needs an ass-kicking. He's a POS to climb into bed with her. Even if he didn't touch her, you can bet he thought about it.
Put another way: would you (who was so drunk you yakked) have been aware if you got into a bed & there was someone else there? Of course you would notice, for the reason Lesa said.
