I don't know what I can do to convince her of the changes
You can't convince her through talking. "Why can't you believe that I have really changed?"
The only way she will be convinced is to see you live the changes day in and day out. Over time, when she sees the improvements stuck, then she will accept they are authentic.
A lot of men get focused on doing something that will win her back, and once they get her back.....then changes he made stop. He feels he has won and stops trying. Then the M is back in the same trouble.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
