We see things very differently. If MLC is a psychological event and in the cases (rare or otherwise) the person manages to work through the cause and gets themselves in order THEN it may be possible to rebuild a new relationship. If both parties are interested, which most of the time the LBS has taken too much damage by not detaching to want the MLC spouse back.
But your stories are about people who were still not functioning. No one has ever used the word; winning the lottery; in watching your loved one blow up your world, be in significant pain, even if one day they manage to get better. It is far easier to just walk away, and there is nothing wrong with choosing that if the pain is too great.

Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
