re: Getting financially screwed in divorce

It sounds like there is already enough money for the kids future to be secured (through 18), so you have the option to just stop being a producer.
Buy a camper and live permanently in a campground, spend your time working out, cooking meat on a pit, taking long walks and pondering the meaning of life. Become so cool that your kids will want to be around you whether or not you’re buying them shite all the time.
At least that’s what my weird arse would want to do.
