Most Helpful Guys
1. You're not in love with him. If he is only a crush, then he is an infatuation, that's not really love, and you'll get over it soon, if you do not, please seek professional help.
2. I don't know what your behavior was, but I think this may be for the best. You'll have some time to cool off and he'll have some time to think about you in a way without you being irrationally enthusiastic.
3. He may certainly unblock you one day. Perhaps you could contact a mutual friend. However, wait at least a week, if not longer before you see if he's contacted you. Actually, make that a week where you didn't think about him at all, or barely at all, before you contact him again.
