Well, what "happened" if it isn't an OW is he pretty clearly is depressed. And taking it out on you. In the first few pages I saw you fighting a lot with him. This will keep him focused on you, and not him. Typical stuff.
You have gone dark, right? (or dim with kids). Best thing you can do. GAL, detach--let them deal with this themselves. And like many here--hope they "get it" before you start smelling freedom out there. That is the "unknown". Just how long it will take.
But a good, short script if you do have any interaction. "H, I need a man that takes care of himself so he can be a good father and husband". Say it and turn and go immediately dark again.
