SF - fwiw, I think your h is very miserable and confused, alienated from himself. Those that are happy - well I think there are two possible explanations: they are not actually in MLC, but just immature people who have walked away from their marriage. They will likely do it again and again, until they realise that relationships have to be worked at. So as each r sours and gets tired they move on. They are freeloaders in the game of life. Or they are in MLC, but those that, as Lissie says, skim off the top of life. They do not wish to look within at all, and never resolve their crisis.
The real MLC, as recognised by many professional writers and therapist, and called by a variety of names, is a search for happiness and answers. The MLCer projects their misery onto the spouse and marriage, and often teh children too. Thus initially they appear happy because they have dumped their projection on to us.
Their selfishness is staggering, and oftentimes they appear to be able to connect with only one other person. SF you have been so patient.
