Hi G. Of course it's sad and if W wanted it could be fixable but she doesn't want to fix it so it's not fixable
I sound like a broken record but so do you !!! Your M is over , W wants to be free and she will not work on the M because she doesn't want to.
This may not be forever but it may so work on you and become someone who you want to be.
G , it's still very clear to W that you need her and while she has you as an option she has no sense of loss or concern over losing you I'm not saying to act different but at this stage ( time wise ) you need to be detaching more than you are
All the above in my humble opinion and I do feel you pain
