IMHO, that's not possible. First, ditch all the no-fault divorce laws. That will solve 80% of the problems we're discussing here. You cheat on your spouse, you get squat. Sounds harsh? That's the idea. If Mom and Dad are both parent of the year and Mom has a proven affair, then Mom leaves without the children, the house and the cash. You play, you pay. Any guesses on the divorce rate under such a scenario?
No guesses, but I completely agree.
