One spouse distances, the other spouse chases. Eventually the pursuer stops chasing and begins to distance and the other spouse moves to chasing.
In the end, like hot potato, one of the spouses is left holding "it"... is the LBS...
And here on this site or reading MWD's books, etc... is often the spouse in mourning... the LBS...
In your case CV, you are here. You currently still associate with the WAS label, yet... you are here...
The reality is... ONE of the spouses (at least) has to stop the pattern. The spouses need to stop blaming the other for their actions (their desire to leave or their reason for not trying to work on the M).
How have things changed for you over the past 10 months, CV? What is your thinking now, about the M?
