I also think OM is not coaching her to say that she does not want to be married to you. My H says the same things, he says he cannot imagine us being together for another 30 years or so (if we live long enough).
Its their own justification for the EA. Once withdrawal goes away, lets see if they would still say that. Then maybe, you can try being the one to suggest an S or D (revenge?knowing they have no one to turn to....just kidding, but I think of that in my angry times).
Seeing my H depressed actually makes me alternate between sadness for him, resentment that another woman can make him feel like that, and gleeful at the same time - its like revenge, well at least he gets to feel what I did a few months back, without me having to do anyting bad to him. So do not act on your anger, sooner or later they will hurt themselves by their own choices.
