When married couples have been together for a while, they discover certain things about each other that are intolerable and these things are destroying their union. They decide that going to a marry counselor might correct their problems. They expect that the counselor will help them to see the “light”. Unfortunately the counselor cannot side with one or the other. They must remain neutral and hope that by guiding the conversation the two parties will come to an understanding.
The most problematic issue is that people are what they are and they cannot change because it is ingrained deeply inside and cannot be modified or altered under any circumstances. It my belief that the three most important words in any relationship are: acceptance, tolerance, and forgiveness. These three words comprise all the requisites for a good relationship.
Oozing Wisdom 
If people would take the time to get to know each other and discover their likes and dislikes and points of harmony as well as dissention it might just reduce the need for marriage counselors and divorce courts. There was a reason why our grandparents, great grandparents and previous generations favored long engagements which is why their marriages lasted. Of course divorce was not common nor should it have been. It runs counter to scripture.
