If you've already apologized, asked forgiveness, and changed the behavior, then don't bring it up anymore.
You work on the marriage by working on yourself. It doesn't necessarily mean she won't go through with the divorce and it doesn't mean that you guys will get back together. What it does mean is that you'll be a better spouse for her if you do reconcile and a better individual if you don't.
You have to let her move out and move on if thats what she wants right now and prepare yourself for divorce. In her mind, you already are.
