And, Yeah, I have to agree with DH...divorce in our society has become the "norm".
It's become socially acceptable if you're "not happy" or if "you need to find yourself".
When you hear stories of people who've been married 50+ years, they put in the work to make their marriages good. They didn't give up and look for greener pastures when things got difficult or when they got bored.
Also, I think people in society today often blame others for their own unhappiness, instead of looking within.
And, I won't go off on a religious tangent, but IMO, (and not to over-generalize)I think where people don't believe in a higher power, that it affects whether they will stay committed or not to their marriage, too.
