I haven't caught up on your sitch lately, but I do see how frustrated you are getting with H. I get the need to plan and all the financial stuff...I'm opposite of you; I'm not the bread winner and had no clue what I would get and how we were dividing things or how I was going to survive. The one thing I did was NOT contact him. So some advice...stop contacting your H.
Plan what you need to and then talk with H about the kids things as needed. Worry about YOUR finances and set up a payment plan that works for you in the worst case scenario...and if things work for the better, you can pay off more each month and not feel the pressure/obligation if it doesn't work out. I hope that makes sense...it did in my head...lol!
The thing is, he hears you. I know the MLC fog is there, but it's amazing what they "do" remember. Stop contacting him. Let him contact you. Protect yourself and I know that some of it you need his cooperation with, but say it once and let it go. He'll remember, Clark did. It shocked me with some of the little things I said or did that he remembered.
So just a summary, stop contacting your H
