I am really new to all of this stuff, but count your blessings in this situation. The fact that she would have dinner with you and offer a hug is pretty big. I mean, it doesn't sound the "all clear" alarm or anything but that is progress! Feel good about it. Keep doing what you're doing (it appears to be working on SOME level) even though it is hard as h*ll. I am going through the same and haven't seen the positive signs that you have yet - though I think your W has been out of the house longer than mine.
I'm wishing you the best of luck and determination.
