Ok so you did all of that. You showed her you aren't the man you were.
Has it really lasted? It sounds sort of like fluff.
You don't call people what you used to, you are being more forgiving...
But on here, in this very thread, many times you have talked about wanting to hurt the OM/neighbor/whatever he is.
You are still angry. That is the type of stuff you need to look at. And those changes do not happen over night.
So the small things frustrate her. Of course they do, if you can do them now, why didn't you do them then? But it will take her time to adjust herself to anything you do and you have to accept that.
"Acceptance doesn't mean resignation. It means understanding that something is what it is and there's got to be a way through it."--Michael J. Fox
