In my case, we would alternate weeks, and keep each other informed about ANYTHING our boys were doing. I did not compensate for their mother not being around as in buying their affection. I engaged them more we played more and I did not shirk my responsibilites as a father. They got punished when needed and I wasn't worried if mom was their favorite for it.
We had a deal that neither one of us would burden our children with our problems. I didn't ask them for information about their mom, and when they tried, I told them thank you but that was a conversation that had to happen between their mother and I and they should not be a part of it.
I kept them away form our problem, and wife did the same. All the while telling them this was not their fault.
