Why does my brother always call me ugly?

A lot of guys ask me out and I don't act like or dress like a slut either, I just act like me. I know my brother shouldn't see me as pretty because that would be weird but he doesn't have to call me ugly all the time. Is he jealous or something? Also, he is my older brother.
