What the hell

I have a friend in school that blames me for everything. I try to be cool with her, but she hits me and curses at me. I think of her as a friend, but I can't take it anymore. Yesterday, we had a meeting for drama club. we had to go or it would be canceled. I was really busy that day and could not go. She comes up to me and says that the play was canceled and now she won't talk to me. It was not my falt. But fine, if she does not want to be my friend anymore, then so be it. we are not friends anymore.
