I agree with Schrodinger, make it an amicable split if she agrees. Nobody ever wins when someone makes it a mission to screw the other as hard as they can out of vengeance. Writing doesn't always convey emotion as well as either the reader, or the writer might like, but you sound angry at your soon to ne ex. Try not to act in anger though. I understand you may not feel like like being fair, but you will feel better about it later.
