Sadhub, I can't really tell you how to make things better between you and your WW. But you are not detaching at all. Everything that you're doing is reacting, you're on her roller coaster. If she's nice to you, then you're nice back. If she pushes your buttons, you push hers back.
Just say nothing and do nothing. The universe will take care of the rest. You need to forgive yourself for what you did wrong in your MR, and like alot of people on this board, you're still holding onto the past - the happiness, the sadness, the comfort. Let that all go, let the pain go and you will find the peace that you're looking for.
Focusing on your children is not going to "save" you if you're doing it to forget about your WW, but focusing on them to be the best person and to be their lighthouse will.
Just cos things are going right, doesn't mean that they were always wrong.
