There are three radical and negative approaches to a troubled marriage:  suicide, homicide, and divorce. 

The first two are considered unthinkable by intelligent, mentally healthy people.  On the other hand, divorce is often seen as a humane way of ending the pain of an unhealthy marriage.  Some have divorced two, three or more times and are still in search of a happy marriage. 
 
When I did the research for the book, Desperate Marriages, I discovered that divorce does not solve problems, it creates problems.  Further, they are problems that never go away. 

The answer is not found in running, but in learning. 

Learn what is behind your spouse's bad behavior. 

Then you can ask God for wisdom on how to respond.  You can be a part of the solution.
