I just believe that marriage as an institution is failing. The basic core family is disintegrating. Marrying for love is a relatively recent development. For thousands of years the family was all about survival. The human race needed the best matches to produce the strongest offspring. The fact that our youngsters are becoming more and more secular and rejecting God is removing the sanctity marriage once proclaimed. Divorce was a no-no.
But where did that all lead us ? To where we are now.
So it's being proven that people go through fazes in life. And the "love" for one person for the duration is nothing more than a failed extended faze. To realize that we don't "own" anyone is the hardest thing to accept. You can do your best but you cannot control if your partner of even 50 years may decide they are no longer interested. So we can go around and " mourn " the death of a marriage but if we don't move forward then it's to our own detriment.
