SD, the basic logistical necessities need focus and it looks like you are following up on the important ones listed here.
I think you had your first major dip on the rollercoaster. That soul eating experience of wanting to make some sense of your W's behaviour - many of us have been there.
Be prepared for more ups and downs, especially when you first see your kids and W. It's normal and to be expected. As others have posted, do not do anything you are unsure of, and definitely avoid confrontations, revelations of intel etc during these times.
Will remember you and your kids in my thoughts. Stay strong.
