I can't believe what my ex did...
What did your ex do?
She was a bitch. She cheated on me, she was so mean to me, and she took some of my things.
I'm sorry that she has done these horrible things to you. I hope this means that you have cut her out of your life entirely, because keeping toxic people around is never okay.
I think it's going to go ok. She can come back but I would never trust her again.
I don't think it's wise to let her back into your life if she's done such awful things to you. Focus on yourself and your friends/family for now. Take it easy for a bit and eventually you will find another romance.
