Why do idiot guys always seemed to have a gf?

I dont understand, like personally I'm a nice guy, I get along with girls, and they always say their bfs are ***holes. Why are you girls with them? I treat girls with respect and would never hurt anyone, and I'm fun, and yet the guys who treat girls like objects or just like poop have gfs. I tried to be an once and they asked me why I was being an hole, I said because apparently you're attracted to . I dunno, its mind boggling, anyone know whats on the go with girls? I think it would be cool if we could get some girl opinions on this, I;d like the hear them.
