That was very brave and honorable of you to get the ball moving, the sooner that happened the sooner she will realize what a mistake she is making.
You seem like an amazing person that recognizes his faults and is doing what is necessary to change.
I know how you feel, we have been there, you didn't want this but it had to happen, just continue to better yourself, each interaction you have with her moving forward she will definitely see a change, keep at it!
