I doubt any have changed because of what her husband did. Several on the board here have changed for themselves, perhaps as a result of their H changing, but not because of something their H did. YOU CAN'T CHANGE HER. Only she can do that. You can change yourself to make yourself more desirable, happier, more attractive etc. That doesn't change her, but it will give her the encouragement to change. What have you done to improve yourself? I know that question has been asked of you multiple times here, but I don't recall ever seeing an answer.

If you are miserable (it seems you are), then it is up to you to change yourself or your situation to alleviate the misery, or else just put up with it. Those are your feelings, and nobody but you owns them, and nobody but you can do squat about them.
