Last night, after reading about the "talk", I put myself in your W's place to see how it might look.
This is going to sound shallow; One of the "thoughts" I had as your W, is that if I don't get a D now, then I'm back to being in limbo w/ parts of my life, especially financially.
She knows that the offer of sharing the proceeds from the sale of the house is a generous one. If you stop things now, she might not be in that position again.
Maybe she wants to go ahead with it, get in a better position, & then consider a new R with you.
Just a thought, & one that might not make a difference to how you feel today. Thought I'd throw it out there anyway.
