If you can manage to stay there, it would be best for D not to be separated from her friends and school. She's already lost a brother and is probably worried about losing anything else.
I understand that this might be beyond your control, now that the child support has been cut, but if there is any way you can just keep things stable for now, it would probably be best for her.
Yes, if you moved to CA, you would probably get a different deal on child support - assuming that CA courts will revisit a Kansas child support order. I don't know how that works. BUT - California is expensive to live in, and friends and family are important. You only have - what - 3 more years, four? - to get through until he can't use the kids to get at you anymore.
Forget justice. Focus on you and your D. Enjoy every day. Get creative about living your life. Set a good example for your D.
