I'm in the same boat, my WW and I had what I thought was a pretty decent marriage, we very rarely fight, we're great parents together, and we've always balanced each other out.
With that said, I understand and accept my part in opening her up to becoming WW and am working through that. I agree that there are moments where the wife I fell in love with years ago is 100% there and present and then there are times where she is completely different.
I don't know where we'll end up, feels more and more like we're headed for D as she shows no signs of wanting to work on the MR, and that's okay. As much as I feel I've dettached and am working on moving on with my life without her, there's still a small piece that is still holding on to what could be if she ever figures it out.
I think a lot of us are in the same boat, living in a bad dream, trying to move forward as best we can.
