I'd like to ask you a few of questions if you don't mind. So far all I've read is you doing this or that to please and satisfy her.
What do YOU want? Why aren't you doing the things YOU want to do? Why are you letting her dictate the terms and conditions of everything?
I like what Steve wrote for you. It's PERFECT to NOT sell the house. Which I believe you don't want to. Cool! The longer you don't sell it... the longer she is going have to pay her share.
Start doing what YOU want.
