Your W wouldn’t be on this site because she doesn’t want to fix the marriage. There is nothing we or anybody can do to change her mind. I suggest you really dig down deep and look at your role in this so this does not happen to you again in the future.
Onward and upward.
Believe me, I am trying to figure things out. I wrote about my 180s earlier. But the most important one is to not neglect my beloved's feelings. Ever. Also to communicate. I have been working on them through intensive discussions with others, not just my therapist.
It's too bad, my STBXW would like the tom 2.0. But she spent the last few years convincing herself I was beyond repair and fell out of love with me. She succumbed to the social messages that Michele decries, that the only way to save oneself is to divorce. Too bad. Her next husband will not have learned DB principles and she will find herself in the same situation.
