Does he like me or does he just want in my pants? :\?

I'm think it's a given he wants in your pants. You can tell that for sure by the way he was acting. But maybe that isn't ALL he wants. As to whether he likes you enough to want a relationshop, I think you should go slowly and keep out of the picture right now. If he is still acting the same and being really atttentive and nice, then he likes you for more than just your body. If you tell him you want to take it slow and don't want to do anything and then his behaviour changes, then he just wanted "in you pants". Watch out for those guys with the bad reps with women, though. He got that for a reason and you don't want to end up just being another girl he got with.
