I think he's in a major MLC and doesn't know what he is doing
He does know what he's doing. MLC is just an excuse. This same behavior is pretty much seen with any cheating spouse. Don't label him with something so he has "an out" for unacceptable behavior. He's made a choice.
I wouldn't file for divorce, but I'd make sure you have all your legal ducks in a row. You need to be prepared and protect yourself. Open your own bank account and remove half of the money. He'll spend you both into the poor house wining and dining this woman.
Now, put on your game face. He doesn't need to see that you are crushed by this or even that you want to save the marriage. As far as he's concerned, he should be under the impression that you don't want him back. If you aren't his for the asking, he may begin to take notice. BUT, he's probably still wrapped up in this affair so he may not be looking that hard. Start working on making yourself happy. You can live without him, and be content, and should start working on that. Take up hobbies. Get active. Enjoy your kids.
You cannot be lonely if you like the person you're alone with. Dr. Wayne Dyer
