Guys being mean to their crush

I don't know why guys ever thought it was ok to be mean to their crushes. The sad thing is that I actually liked the guy. He threw paper at me today and I realized how truly dumb I was. Why would I ever like a guy whose mean to me. Being mean to someone because you like them is middle school. I now realize that I would never like a guy whose mean to me. I know he likes me, but now he will never have me as his girlfriend. Its a shame how truly ignorant guys can be.
