Whenever I find out a girl is interested in me, but I don't return her interest, I've frequently found myself enjoying her sad feelings.
I don't know why, but I just... enjoy it, for some reason. XD
I hate feeling like this myself, but whenever a girl gets an unhappy crush on me, I enjoy it.
I highly enjoy it; the sadder she is, the better.
Sometimes I even do my best to be as charming as possible whenever she's around, so she will start longing for me even more.

Am I just being sick, or is this a natural behaviour?
