I'm hurt.

Ok so I like this guy. Someone told him that I like him, and people have been walking up to him and telling him I like him. So after school today, he walked up to me and was rudely like hey girlfriend and then he looked at my best friend and said never in a million years would I date her(talking ab me). She said oh I know. Then he asked her out and she said yes. I don't know what to do ither than cry.
