Perhaps slower to trust?
I am far more trusting of people and the Universe, and faster, since BD than I ever was. But it may only have to do with being older.
But that's our own growth spurt, not an effort to fix ourselves to lure a wayward spouse back, or to change the circumstances that precipitated their exit... that's crazy talk, they left because of their own issues and not ours, and they'll come back when they fix their issues, if we haven't outgrown them by then.
This 100 times.
A crisis that includes hermitages and fasting is much easier to deal with than one that includes OW, spending, spending, spending, etc. At least I think it is. And people will see that sort of crisis as a crisis. Or, at least, as someone has become a little strange.
I don't think MLC is affluenza. It's a disorder of the mind; depression, in some cases. Not a product of world or time. We have always been this easy to break.
So far, I have never meet anyone that couldn't afford to have a MLC, so, I think it has something to do with money. That it is depression I have no doubt. Not that it has happened a lot in the past, The Odyssey is a MLC journey and it is set in the 12th century BC. So is Dant'e Divine Comedy, from the 14th Century.
We're easy to break, but modern life breaks us more. Depression had been on the rise and will keep being. People have everything, but are never satisfied. There is a difference from past decades/centuries. In the Western World, and other parts of the World if one has money, people have too much (I am not talking about millionaires/billionaires). In the past, only a few had too much, some had enough. Most had less than enough. They led a life of sleep (often) barely, work, and a festive day here and there.
As for run, humans can run without going anywhere and have often done so. Drinking, drugs, sex, war, etc. Run/escape alone does not equal MLC. Like not all affairs are MLC affairs.
