Been married for 24 years. My parents are deceased but never divorced. My in-laws are still married. All four grandparents stayed married and never divorced. My wife and I both have siblings that split up.....and their kids suffered from it. That is probably why I'm still married today. We've had a rocky road, but both of us have worked through it for the sake of the children. Now, both kids are in college with very promising lives to live. Not saying they wouldn't have turned out as good had we split, but statistically speaking kids from divorced households tend to have more issues/problems.
The breakdown of the family unit is the biggest reason this country is going down the crapper IMO. No statistics, just a hunch.
