It's easier than that...
It's his house. Period. You don't have to pay at all unless you live there. Paying his bills is part of what got you here in the first place.
You divorce, you pay your bills, you DO NOT pay his bills.
I've reconciled with my wife and I don't pay her bills anymore. I make three times what she makes so I pay utilities, but she pays internet and half of our rent (and we split groceries). No matter how much more money than her I ever make, I will never return to paying all the bills. Ever.
I truly believe if I were to start paying all the bills I would be enabling again and therefore endangering her recovery and mine.
