Still Trying, I agree with you that you have no real choice but to separate. I would be more inclined to fight it without the house sharing arangement that you have. I am currently in a similar situation of house swapping, which by the way is good for the kids if nothing else.
My situation sounds very similar to yours with the exception that my W has said she wants a divorce, but makes no effort towards getting one.
I have the same issues W wants me to be passionate for her and to hold her on in highest regards, to be thoughful, etc. But of course will not let me do any of it, but instead thinks I can't change. I don't have an answer for this I just really don't know what to do here.
