I really do not know that answer. There were times when i thought things were getting better but it was just us being nice to each other. To see the mission she was on when taking on the move solidified that for me. I know your situation that W wont leave and makes me wonder why. If she was so miserable with you then why really stick around.
I think my wife felt she had to move because 1. she knew i wouldnt, 2. I think she associated me with her not being happy. By her doing that she first said she needed space, that didnt cure her happiness, then she said I think we need to separate, still no cure, then she figured the next step is separate living. If this doesnt cure her happiness then she will either determine she needs a divorce or maybe realized she either needs me or someone else.
then you can look at the complete other side of this and say she found so much happiness with the in house break and separation that she needed to make it permanent with the move.
I dont buy the last one. I know many of the other stories where things have either worked out or they tried that the living separated and there was a period of darkness before anything came about. I am not looking for too much on that rather than just getting through the initial mourning of the relationship and then carrying on with my life.
all the best bud.
