Yep, sounds like a crush to me.
Dusty sounds like a jerk to have actually rejected a hug from you.

Some guys, at this age, are just in their own bubble or something. There are a lot of really decent guys out there, and then there are a few of these types that know that they're eye-catching & their egos seem to fly above the roof.
I know how hard it is to let go of obsession, so please don't let it get that far. Let go of Dusty now. He isn't worth your time or heartache. There are a lot of decent guys out there, just wishing that they could get noticed by a pretty girl like you.

Focus on taking care of yourself emotionally and physically. Before you know it, a decent guy will be interested in you & you'll be emotionally available!
