Im feeling impatient and annoyed that I have to change
Why are you annoyed that you have to change? The change should not be used to win her back. If that is your motivation, then it causes you to have expectations in her. When she doesn't respond the way you thought she should, you feel there's no point to change.
I think this is an issue in yourself you need to examine. The changes are to make you a better/improved person. That is for your good! Why does it make you annoyed? If you don't think you should have to change, then don't. B/c you won't stick to any changes with this kind of attitude. Maybe that is what you need to deal with now.
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!
