OK, so I quite like this guy at college, but he's got a girlfriend, and I'm not sure what I should do. I don't see him very often (only 1 subject together and he goes to a different college for his other subjects) but when I do he's really funny, and sometimes in lessons I look up and he'll be looking at me smiling - thing is I don't know if this is just because he spaces out and I happen to sit in a bad location, so that when he stares it seems like he's looking at me?! (although we have lessons in 2 different rooms and I've caught him doing this in both rooms, but then again I do sit pretty much opposite him in one room) Anyway, he's got a girlfriend, who as far as I can tell, he's been with for quite a while, as in since school, and I would feel really bad if I did anything to mess things up between them. I've never really spoken to the girl, but as far as I can tell, she's just a really nice person, and I don't want to hurt her.
Sorry for the big long rant people, but any suggestions?!
