the wanting/wanted dichotomy

I've noticed a perfect negative correlation between wanting something and the ease with which you can have it. For example, all the guys I really don't want to have anything to do with right now are crawling all over me, yet the ones I actually want want nothing to do with me. Why does this always happen?

Right now, in addition to the classmates I've been turning down, Asshole seems to have renewed his interest in me. Nevermind that we are several hundred miles away from each other and I'm completely uninterested in his micro-penis. Sometimes, I think men have radar that picks up on your complete lack of interest so they can then go out of their way to remind you they exist. I bet if I could create some sort of repellent for this, I could make a fortune...
