I don't have many friends either. In fact, there's only one.: my boyfriend, he's my best buddy and I wouldn't know what I would do without him.
There are other people who might think I am their friend. But after a short time, I lose all interest in them. It's not that I don't like them, I WANT to have friends, but their presence starts to bore me and eventually gets annoying.
So I start to avoid them, tryng not to be hurtful. It's not their fault, obviously there's something worng with me.

I guess I'm doomed to have distance-friendships without too much contact.
