Its okay for ranting, that's what I'm here for.
Well..maybe he just doesn't know you. If you two have mutual friends, try and hang out with him and other people, so he can get to know you. New people can be intimidating. Don't be depressed about this, it's not worth is sweetie <3
I'm sure once he gets to know you he'll like you just fine
and if he doesn't, he's obvioudsly not the one. There are PLENTY of fish in the big, blue sea. Hang in there darling. Oh, and if you really want to you can post in Realtionships & Dating.
