I've just gone through your thread and really feel your pain. My H and your H said pretty much the same thing: eg. that the way I spoke to him was disrespectful (Im still figuring out what and how is it disrespectful).
Please take comfort that he has not taken any actions yet, so anything can happen. I like Cindy's advise to BELIEVE. A lot of people told me to just ask him to let go, a lot of people has tried to convince me not to put up with this kind of crap anymore. I also tried to convinve myself that what I am doing is a total waste of time, that H cant really make up his mind and cant let go of OW. But soemhow in my heart, I know D is not the answer and I am so reluctant to beleive that is my fate.
I am suppose to move in with H next week but the closer it gets, the harder it seems coz I can see that now he is having his doubts. After reading through your sitch, maybe I will cancel our plans coz I know tht he move in only to have him walk away again.
Take care...
