I know several couples here where I live that are miserable with each other. Divorce among the friends is increasing.
There is just no help for families that are in trouble. I have tried to help a few of them by suggesting marriage retreats, books, counseling, etc. They respond with the usual "That worldly stuff can't help." They are totally closed to it. What are they supposed to do, take counsel from a worker who has never been married?
I think it stems from a fear that other friends would find out that they were having trouble. (Which means you are slipping.) I can't stand the way the "truth" has evolved to make everyone afraid and live in fear.
When a person believes that their group is superior to others and they have a form to maintain, this makes it nearly impossible for them to get help. The belief that they are better than others is wrong. Trying to maintain a form made up by the workers is impossible. As a result, they make bad choices and have to live with the results.
