I'm not an expert and have only been in this sitch for a month now. However, I feel from reading your thread that it is because you have reached a mental state where you are ready to let go, she is warming to you! I think she is realizing she will lose you and she would rather keep you close until she decides or sees enough changes in you. In my opinion, the shift in mental state for you is what is intriguing her. Perhaps one of the EXPERT VETERANS can offer their take on this. But I would say don't give up! You might be on to something here.
