Wow it seems we have reached exactly the same point on this. It is somewhat freeing which helps with the detaching. I am basically where you are on not necc caring whether they want to accept the good and keep resenting the bad. But sometimes resentment just never goes away for some and you can only control the new you. Keep the head up and power through. I wish you good luck.
