You are not hearing me. Why not have them spend half the nights with you? You are spending all the time during the day, after school, etc. with them, then letting them spend most nights with her, thus shooting yourself in the foot. Too much back and forth with the kids. They should be on a flexible but regular schedule with each of you.
I understand your concern about the legal bills, but let me give you an eye opener:
My D cost me $14k. If I had agreed to what my exW wanted in custody and support, it would have cost me $134K in CS until my D11 was 18.
It was never about the money, I wanted to be as big a part of my D11's life as possible. If I was going to have my D11 half the time, why would I agree to pay the same amount in CS as if I didn't.
