Here is my take on this. I have observed a couple of other relationships that turned to divorce. I guess in mine I would say my W started going out with me more, and trying to do things I like in the past year prior to bomb. Another friend of mine's W had surprised him with a trip to a Notre Dame game (his dream vacation) about 6 months pre-bomb. I would say about the ML with your W pre-bomb she was just trying her hardest to make you happy....... She was fighting her negative feelings and the reality that your relationship is not where she wanted it to be. She didn't marry you wanting to get divorced. So I would say her love was just running on empty and she was trying her hardest to change it. IDK just my take.
