Am I in love یا have a crush? I am not really sure.

So, there is this guy who I think I like since fourth grade. I always think and daydream about him. It's kinda' weird how he had two girlfriends, that I know of, NOT at the same time, and it doesn't bother me at all. Nobody knows about this and it is kind of hard keeping it a secret. I told my cousin when I was in fourth grade that I used to like him, but the truth is I still do. Anyway, I'm in eight grade now, and this is the first سال I have classes w/ him. He doesn't talk to me, it is either because he doesn't know me یا because I'm really shy, and he probably thinks that I won't respond to his questions.I'm not sure if I like him, I like his dimples, the way he laughs and smiles, the fact that he is an athletic, and he is really smart. In fact, one of my classes I have w/ him is PreAP Algebra. Please help.
