Also, remember H gets to write off spousal support on his taxes, while you have to pay taxes on it as if it were income. Remember that as you calculate scenarios.

My ex's tax bracket is such that he gets almost a 50% tax break on the alimony he pays me, so it's not nearly as bad as it sounded to him, I'm sure. Maybe if you could point that out to your H, what his true after-tax cost of spousal support would be, maybe he will be more cooperative.
