I've read that sometimes the WAS has to go through a period where it's fully and completely over in their mind before they can re-commit. Maybe that is what is going on in her head? Maybe she had to say, this is really totally over, before she could start moving closer to you? But it seems like normally there is more time between the declaration of it's over and the motion towards recomittment. It's also possible that she is just kind of yo-yo-ing around. I am not sure either...
But I know you are strong and will DB amazingly!!! you are doing such a good job, bbhopeful!!
