What have you done to work on yourself since this began? What have you changed about your own behavior/actions in the marriage? The problem is something was "broken" in your M which led up to all of this. Unless you have identified and worked on where you came up short, you will not be any different in your M and will end up in the same place you are now in just a short while.
I am not discouraging you. It is great she seems to want to work on it. That is a big big step. I will defer any advice to others who have been down this path. I just want you to remember that you need to continue to work on you
Good luck!
