I know the fighting gets you where you live, but I want you to consider this:
Think about the infertility patient who just got a negative test result today. Her dream of being a mother slipped through her hands again. That woman would do anything - ANYTHING! - to hear her children fighting in the next room. Once upon a time, I was that woman.
Think about the woman who would do anything - ANYTHING! - to have a husband who does not take out the trash, squeezes toothpaste from the middle of the tube, or leaves the toilet seat up. Right now, I am that woman.
The love your kids have for each other is down in there, somewhere. May not always see it, but it's there.
