My W is going through one right now. She had an A with her boss twice her age, did things she always said she'd never do. Had the traditional triggers of a close family member dying, loss of job, newborn child, etc.
All this leads to her re-evaluating her life and thinking that she better do something about it to make her happy. Well first thing she did was cast out our M. Blamed me for alot of things that wasn't true, never admitted her A, being depressed, etc.
During this time I've read everything and anything about MLC and it all comes down to this...
YOU can't change their behavior or what they will or will not think. All you can do is take care of yourself. Imagine MLC like a hurricane, destroying everything in it's path. You have to be the one in the bunker to protect yourself and wait till the storm blows over. You are going to be the one who is going to have to pick up the pieces after the storm is over. So while you're in that bunker, you make sure you have the supplies necessary to get yourself prepared (self-esteem, confidence, inner strength). You're going to have to do all this on your own because your MLC spouse is spending all their emotional energy on themselves.
After they hit rock bottom, you're going to have to be the lifeline that's going to be the emotional light that guides them back. It's their choice to take it or not, but at least you know you've weathered the storm intact as a whole human being.
Make sense?

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
