I think the point of the article, and a lot of the current research, is the importance of re-thinking divorce in "low conflict" marriages. Yes, there are truly awful marriages that exist. Even when children are involved, it is probably best for divorce to occur in those situations. I'm sure you've seen the discussion from posters about adultery, abuse, addiction, etc. People do, however, seem to be rethinking those divorces that occur because of a "lack of connection" or "falling out of love" or "not meeting each other's needs" or those other Lifetime TV pop psychology type of frivolous reasons. From what I've read, it appears to me that those who oppose divorce even in cases of abuse, adultery, addiction, etc., are a distinct minority.
I know I would hate to be married to someone I did not love or who did not love me. But knowing what real love is like spoiled me.
