"Like" or lust or infatuation?

I like a guy & for over a year now..he IS good looking but that's not the only reason why I like him. We're just friends, but ..well, whenever he says something nice to me, or just talks with me, I feel all warm and bubbly and nervous (is it endorphins??) And when he's mean, I take some of the things he says to heart and few times I cried b/c of it. Is it possible to have these feelings and be lustful? Or infatuated? I thought lust was only caring about how hot or good looking they are and that alone. But I DO care about him...what is it?
