Khudoo s lot of this sounds like mine W and how she is behaving. I've only been dealing with it for about 2 weeks now and I can imagine how tired of it you must be.
You raised a good question that has crossed my mind several times. One of the issues my W has was my lack of interest in her job which is very important to her. It wasn't really lack of interest, I think I was actually jealous of her since she was interacting with professional adult people while I was at home with the kids and animals. I hoping someone answer on the "normal pleasantries" question. I can say that at first W was not saying goodbye, goodnight, etc but now after only a week she is.
hang in there, from what I've read it is a LONG haul but you have to recognize the small victories and use them to keep you going.
