I would be very comforted by her wanting "that couple" and it sure sounds like she would like it to be with you.
Who the heck knows why she's still moving? I think pure stubbornness can cause people to follow through regardless of feelings. Ego, fear...doesn't matter. If she wants to work on herself great. And, she cares what you think of her. And, I LOVE that you have turned it around (or perhaps it has always been your take) that you are looking for changes in her not just the other way around.
Good stuff. I think your confidence will be very enticing, especially to a woman who is feeling so insecure. I like that you can be so honest without fear that it will push her away. Seems like you've got a very healthy perspective. I'm a tad envious...but at least I've got you counseling me on my sitch.
