Man, you couldn't have done anything more differently to change the course of action on her part. You DB'd like a champ and made huge improvements to yourself. I know that this does put a final nail for the small bit of hope that you tucked away, but just like in the past, feel what you're feeling and let it pass.
I agree with LH about the summer comment from her.
I believe she's still in her journey and just like BD, she might think that getting the D will finally get her to where she wants to go and her problems will go away. But we know that getting a D isn't going to help with that if you've not handled all your $hit and come to a place of peace with yourself.
Let her ride out her journey and that's all the best you can hope for. The future is still not fully revealed and this D process will take months. So, stay the course with yourself and see where it leads.
