Here's the pathology:

I like people who like people that I like.

I don't like people who like people that I don't like.

I want to like people who like people that I like or don't like people that I don't like.

I don't like myself.

You don't like me.

But since you don't like somebody that I don't like, that makes me want you to like me.

And this hurts that you don't.
