How do i get revenge on my crush?

Ok, i know this may sound weird......but, i used to have a crush on this really cute and sweet guy, but since hes moved away, ive grown to sort of hate him. I don't know why, maybe since i cant have him? (he lives 6 hours away) well, i dont know, but how can i get revenge on him? More info to help: he has 1 bro and 2 sisters, he likes golf & carpet ball, can be kinda shy, and is very good at gymnastics. HELP! im seeing him at summer camp, and may be seeing him another time at his house over the summer.
