As for your h, continue to give him space and time. He's still feeling his way along and trying to figure things out for himself. I do think your changes have been great and he may very well feel more comfortable in the home right now. Letting go is very liberating and he may sense that you have dropped the rope a bit.
Keep the focus on you and your children. I think you are doing great!
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.
