Dave, I have been getting the same thing. I have completely given up and have not asked W to do anything with me for a long while. Now that she sees me getting a life, she keeps trying to be a part of it. She even asked me to go with her to a couples event. No big deal, but still a big shift.
I think this has more to do with the whole MLC than really wanting to be back with me. She definitely has not shown any sign of being attracted to me. Maybe some similarities to your sitch??
Anyway, it doesn't matter much...just stick to your path with heart and she will either follow or not!
