Most Helpful Guy
Well women from 7th grade usually look totally different then when they get to 11th grade. You know, the develop more or look better most times. Maybe he was interested physically in you, but then after getting to know you or whatever his interest in you kind of dwindled and decided to pursue other people. Or, he was interested in pursuing you, but then friends of his maybe started bugging him about going after a person like you because you aren't the type of girl they usually are interested in or should be seen with. High school is very "clicky" and very judgmental on who you are seen with or whatever. That's some possibilities of why he was like this. It's not nice, but sounds logical. Or if you are open to other views, I'd consider maybe Keke-101's view. You must have been interested in him through out your schooling with him or else you wouldn't notice as much that he finds you interesting from 4 years ago. Or he was part of a crowd that you wouldn't really associate with and that he did and now he noticed you for some reason. At any rate, you probably won't get an answer from him on why the sudden change unless he initiates contact with you. So maybe just take what you've learned from the experience and go forward. You obviously have something about you that gets attention from men now that you didn't before. You just have to build on that and find better men.
