I got drunk and made out with my roommate! What do I do?

Well usually if you are drunk, you kind of do whatever and end up doing all sorts of things..This may have been the case but then the night after she might have realised that she really does like you and it wasn't just because she was drunk.. Tell her how you feel i.e. you sort of like her. If she smiled, it means she DID remember and she isn't guilty she did it :)
