I am very sorry to read that he is still h@ll bent on a divorce. Ah, yes, your xh is one happy clam right about now because he thinks he's going to get everything he wanted and you will be the one that will have the full responsiblity of raising your children. Of course, he'll promise you the moon, because he does not think you will challenge him on anything. Let's just see how happy this clam is when he finds out how much money he's going to have to fork over for support, etc.
Oh, btw, a majority of them are this way until the euphoria wears off and they discover that you and the marriage are not the issue. I just love how they all continue to want to be best friends with us! Being best friends w/them is so totally different from what we consider best friends.
Please, please take care of yourself. Do what you have to do to protect your assets. Please be sure you get what you are entitled to and not one penny less. It's expensive raising children and moving, etc. Do not feel sorry for him. This is now a business deal gone sour and you, as the other partner, need to protect yourself financially.
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.
