Ben, this is awesome!! DBing works. There is another poster here that has been headed to D for over a year, and suddenly in the last couple of days, got a message out of the blue from his STBXW asking if they could put the family back together. DBing does work, when you do it well.
However, as I told him, tread lightly. Lots of people in your position ask "How will I know when she really wants to R?" The answer is when her behavior is consistent over a long period of time.
But this shows some promise, just keep DBing. Don't revert or you will be setting yourself up for BD #2.
Has your W always been a bit of a liar, especially to herself? I do believe that she convinced herself that she removed her ring to put on lotion. And I believe that she did put on lotion. But I am also sure that isn't the first time she ever applied lotion, removed her rings, and then put them back on. Not putting it back on, in light of the recent trouble in the MR, is just too big of a coincidence. Just something for you to consider.
Oh, and keep going to MC. I would also look up touch and talk charges and maybe slowly implement them. Also, I would highly suggest a weekly date night. And not just going out to dinner, but actually getting dressed up and going on a date like you did when you were courting her.
