This guy I have a crush on thinks I have a boyfriend!

If you like a guy, don't carry around a binder with pictures of a guy in your realtive age, hugging or dancing, uncle or not. he'll think you're taken (and since I see you're under 18 and the guy might be too, inferring he's young, he'll move on to someone else).

i don't know how you'll convince him. show him a family picture with everyone and uncle jimmy? or pics of you guys when you were younger, together - for comparison. once he'll see you go through this effort to prove that uncle j is really your uncle, he might know you like him. but guys also overlook things like this. that's all I can tell you for now. Good Luck! :D

Ummmm... That's a toughy... I would say maybe if jim goes the same school, have him come and verify that he's wrong. Like just find a way to prove it. If not, just give hints that you're still available... Touch him often, talk to him, make eye contact a LOT. But don't come off too strong. Say something like "I wouldn't date him anyway, I'm interested in someone else". And what's always fun is driving them insane trying to make them figure out who you're talking about. Ha.
