Your goal should be to spend as little time around and near your W as possible. Come up with a child care plan. You will care for the kids on Tuesdays, Thursdays, and Saturdays. And every other Sunday. She is responsible the rest. (She needs to get used to this as this is what D will look like.) Then on her days you are out being busy.
On the days that are yours, if she is there interact with her as little as possible.
Be busy. Busy busy busy.
