Mom's don't deserve child support any more than dads do. Federal family law begs to differ, but I believe we should be equal parents across the board: time, money, and custodial rights.
What I've got is my state of happiness and peace. I no longer fight with her about anything. I no longer ask her for anything. I keep my communications primarily with my kids. As far as I'm concerned, she's no longer the superpower she was.
I wonder, someday, will they ask how the divorce happened? Will my adult kids want to know who's idea it was to break up our family? These are conversations I could never have with them unless they asked.
Co-parenting is a cooperative relationship. When one of the partners decides to be uncooperative it changes the dynamics. However, as a positive parent, you can be the bigger partner. Choosing the positive is about every aspect of your life, and your kids are the most important relationship you can manage.
For the last years of his life, my buddy will do whatever he does as an old dog. I will watch him zigzagging around the back yard and try to remain happy for him rather than sad for him. I will love on him as much as I can. And I'll be aware of how my emotional attachments and complaints are mine alone. He's a dog.
