Resentment is the core in a WAW. She has to want to let go of the past. When she admits to herself there is absolutely nothing you can do about who you once were.......and stops blaming you, and respects you for making change now, then she will be better prepared to think about a possible relationship. Right now, she doesn't want to let go. She wants to be angry at you. Maybe she is showing you there's nothing you can do to control how she feels, IDK. I just know she's not ready.
The tighter you pull on that rope......the more resistance you'll get.
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!
