Sadly, what you just said is all too true.
Marriage is an institution that was put in place primarily to protect children. However, a thing called the Oral Contraceptive (introduced over 50 years ago) kind of changed things somewhat!
Stubbornly still trying to enforce laws in the 21st Century that were developed many millenia ago by some nomadic desert chieftans is a good recipe for disaster. So much for true happiness being possible only if you "do things God's way."
