Agree w/ the others, let the score card go. That's only a recipe for friction that will affect everyone's quality of life.
Also, when there are children involved, my attitude is give a little more than you might to keep a healthy, peaceful co-parenting relationship and so that kids know you dealt fairly and generously w/ your S, despite their being the one who walked. It will pay dividends in the future.
