Don't get back with her. Everything that used to be between you guys is dead. You need to let it go and move on. A month isn't long and your ex is definitely rebounding. She's angry at you and she for sure won't give you a second chance. But she will watch you embarrass yourself as you chase after her. That's all it is. I would move on.

Man, this is a shitty relationship by the sound of things anyway. She is a petty person. Why on Earth would you waste more of your time on her?
