Treese, It appears that you are getting a handle on the no contact/dark side of things. I think you will find that the less contact you have w/him, except business/child issues, the better. You do not need to be sucked into his drama.
As for Christmas, he most likely will not make mention of it until the last minute. They've lost all concept of time in the MLC fog. It's the here and now and they mostly certain don't think of the future. Do not change your plans for the holidays. Proceed forward and if he contacts you about visiting w/the family, set up a time and go from there.
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.
