No couple is without friction. Arguments, discussions heated or not are part of the healing process. But, for you, as a parent or as a child, how much was or is too much? How did your parents handle it? Did they shield you from it? How 'bout you as a parent? Do you go out of your way to not let your kids see and hear the worst of it? Does your partner see it the same way? Do you believe that the way you were brought up has had an effect on how you see this issue? What effect does their parents' arguing have on kids?
*asking for a friend. No, ha, I really am. My wife and I wore each other out years ago.
