I only took a few minutes to read your last few posts. My W has all the same signs/symptoms, and even refers to the same MLC book, apparently.
We are friendly, but now the attys are getting involved again after 8 months or so (attempted R, where W just kinda rode it out, but didn't take any steps). A month ago things were looking up for us, and we were just starting to piece...but then a small incident occurred and she's now on the big D highway, once again.
Mine kept doing the same thing as yours - she'd drop the bomb again and again, but not take any action. Must be a tactic taught in the MLC guidebook.
I still sense some ambivalence, but the heavy lean is towards divorce right now. The date is only a month away, and I am almost to the point of accepting it. I am like you, I will not give up, but maybe it'll take a D for her to see the other side. After that, I am not sure where I'll stand on wanting her back.
