She could see the changes I made, but thinks it's too late. 11 years takes a lot to undo. She needs this time apart to realize what she has.
But she has had a year and a half, right? Has there been a softening of her position over that time, or has it been "too little, too late" the whole time?
If there has been real progress over that period, then maybe it needs more time. Then again, maybe you need to tell her:
"I feel that our relationship can work, if we are willing to work on it together. But we've been apart for over a year now: I can't wait forever for you to decide. Therefore, I'm going to file for divorce."
