That he tried to have sex with you when he was drunk doesnt necessarily mean that much. To be honest I can't really tell if he likes you or not either. It depends what sort of guy he is. If he is shy by nature he may well like you and feel rejected. However most men would not interpret you hooking up with him and dry humpinh him as anything like rejection, just because you declined to go all the way. Personally I would have taken that as a big green light. It is part of the game for the woman to turn down sex the first few times, after all. So I am against the grain of most of the other responses but this is a male's perspective. And I think your wait and see approach is the right one. Let him show his hand.
Is it burnin'? Well, f-ck, now you're learnin'.
