I ignored that and just asked him to re-confirm about not paying the mortgage. I said, "With the decrease in support being about $1,300/month (I think - haven't crunched numbers yet), I'll obviously not be able to pay the mortgage. Just double-checking that's what you still want me to do?" He wrote, "All up to you. I give a f**k about the house. . . .
God, what a moron he is to put that in writing like that. Yet somehow a beautiful thing.
You might have some good (or less-sucky at least?) options here then.
