There are two key reasons why the divorce is high.
1. Human beings make mistakes!
No one disputes this fact except for when it comes to (choosing) the "right person" to marry. Intellectually we know not everyone dates or marries the right person for them self. Oftentimes people get married before truly knowing who they are marrying. Then there are some who never sat down to figure out what they wanted and needed in a mate for life! And then there are others who marry someone who flips the script on them down the road. It's not uncommon to hear someone say, "He/she is not the same person I fell in love with."
2. Oftentimes people get married for the wrong reasons!
Some examples include unplanned pregnancy, an ultimatum was given, all their friends were married or getting married, they reached a "goal age", just got tired of being single, been in a relationship for a couple of years and thought "Why the hell not?", someone joined the military and was about to be shipped away so they wanted to tie someone down in order to ensure there would be someone waiting for them, and other's have been known to (marry people they did NOT love) for money or to get out of their parent's house.
Everyone is entitled to have "deal breakers". In fact if one does not have them odds are they have low self-esteem or do not love themselves. Just because you marry someone does not mean you have to stay with them if the relationship becomes toxic, violent, or one's mate is cheating, not living up to promises they made, verbal abuse, abusing your children, stealing the family money, becomes a drug addict or alcoholic, stopped having sex or being affectionate towards you. There is no virtue in being someone's doormat!
Lastly it is (women) who initiate 66% of the divorce filings in the U.S. Speculation is it's due to the fact that women of today have better career opportunities and more financial independence than women of the earlier eras. The more "options" someone has the less crap they're willing to put up with! :-)
Too often people say getting divorced is the "easy way out". Most of the time people who say this have never gone through a divorce! The truth of the matter is it's a whole lot easier to get married than it is to go through a divorce! It takes courage to admit you made a mistake and start over again.
"There is no amount of (work) or (communication) that can overcome being with someone who does not want what you want for the marriage." Awhile back I wrote a hub about commitment. https://hubpages.com/relationships/commitmentisnot...
