OK, so I'm going to be fully honest with you. You screwed up. Big time. But if you truly feel sorry for what you did, then apologize to her. It's not the end of the world. But for you to say those things to your friends, is, well, horrible, if you feel sorry for what you did, then you can change. She may not want to be friends with you anymore, and that's understandable. But never do anything like that again.
