If he can't afford to pay you alimony and child support and keep the house, or let you and the children stay, he'll have to sell the house. It is not your job to protect him from the consequences of his choices to the detriment of you and your children. Seriously!
It is a mistake many LBS make - go along with unfair settlements because they're hoping that if they're nice enough, their WAS will change their minds. Unfortunately, a WAS has little respect or empathy and will take advantage of their kindness and you will be left with a settlement that will shape your life for the next 15 years. Please don't!
You will need a L - it doesn't matter what your H wants. He's not looking out for your best interest.
There is nothing contradictory in looking out for yourself and the kids while being open to restoring the M. It's like buying insurance - you're not planning on the house burning down, but you want to be covered in case it does.
