I tend to agree with Jeff. I think what he needs is a good dose of what life without Michelle is really like. I would seriously curtail all but absolutely necessary contact now. Then IF he decides he's made a mistake and wants to explore reconciling you can decide if that is what you want and under what terms.

You are a veteran and know the drill to keep your sanity and mind off of all of this stuff constantly - GAL, etc.

Sorry you are in this situation.
