I understand you, divorce is always very difficult. Ordinary life is collapsing and you do not know where to go next.
And especially difficult because of the children.
It's great that you want to keep seeing them often. Because I know such men who after divorce almost do not see their children. It was as if they had divorced not only their wives but also their children.
So try to see your children more often, at least a few times a week. Because it is also very difficult for them now.
Find someone you can talk to, you need support now.
