Welcome to the Board and your own thread. A few observations, if I may.
By your original post, you sound wired very tightly. I get a sense of definitely trying to keep you emotions under tight control. You are trying to confront this objectively and logically and intelligently. That's great, but dealing with a spouse in MLC is like trying to potty train a squirrel.
Nothing about them is either logical, objective, or intelligent.
I'm not saying "When in Rome . . .", I'm saying you will drive yourself nuts trying to keep all the ducks in a row.
The only ducks you need worry about at this time are your own. Detaching, while hard at first and at intervals, is the most wonderful thing you can do for yourself, and for your kids as a parent.
Do whatever it takes to mentally remove him from the picture in your brain as much as possible. It's you and the kids. Period. Removing yourself and the kids from his hurricane life right now is the most protective thing you can do.
Hang in there.
