You two are divorced. In fact it would be usual that everyone lives separate. The easy thing to do is: don’t tell until everything is fixed. He keeps living where you currently are, you find a place nearby (which is a courtesy, actually). Nearby for the kids, that they can visit you both without much struggle, but separate for your well-being.

Interesting. I absolutely would horrify people. Especially children. Like ruining their sleep. Mess with them until they are admitted to the funny farm. Grow a habit out of that and do that over and over again, in different areas of the world until I become a legend of a nightmare that actually comes true.
