Bea, He heard everything you said, but in his mind, he's going to do it his way. He most likely didn't like what you wrote, so he going to show you and the children that they are going to tow the line and work w/him. I'm afraid that unless your children and speak up, he's going to run right over top of them and yes, if they do move to that apartment, he's going to expect them to be best buds and do everything together and that they will have an open door policy of them dropping in whenever they feel like it. He's still wanting to appear the best father on earth and unfortunately, he's not going about it the proper way. He doesn't get it.
He's still in crisis and I suspect he's going to be one of those that remains stuck. Bea, you'll have to step back and let your children deal w/him because the more you get involved the worse he'll be. As for you, no contact is the best way to go. I'm very sorry he's behaving like this.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
