Job, except the runaway behavior(distant) during midlife crisis, is it true that they been really selfish ?
Not Job but I am sure she will pop in and offer her insight too. Yes it is my experience that most MLC'ers are very selfish. And most LBS's are codependent conflict avoiding enablers. So it really was a marriage where the two people fit together perfectly. Until that doesn't work anymore. Then explosion bomb drop and MLC.
As far as the stages go I warn you no one studied these more than myself. I kept looking for any sign that would explain all of this and where she was at.
I was convinced my wife had gone through every stage and could point at each sign. That FAILED miserably. Your spouse is likely in REPLAY and any change in this will not be known until quite a bit in the future when you look in the rear view mirror and see where you have been. For now - Let GO - Live your life "as if" and don't focus on the MLC'er because a watched pot NEVER boils.
