FWIW, it looks like MLC H needed space and time, and took it. He monstered about the kids’ education and homework (yes, projection of his past), and now wants nothing to do with the kids’ education. Such confusion and flip flopping. I feel for the kids. Of course, they are fed up with it/him.
Well done standing your ground.

Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
