I am glad you had a good meeting with your soon to be ex wife. I know it is a hard situation. My ex husband is still after 5 years trying to make my life difficult, but only because I had the audacity to leave him. Oh well. I hope it continues to go well, and I encourage you to do everything in your power to make sure it goes well, because your kids will be the receivers of anything that happens, good or bad. You already know that I am sure.
Nonetheless, good luck and keep us posted on what happens.
