I came across this quote today.  I like it.  I acknowledge that there are exceptions for abuse or other extremes, but it is a sound principle we can all do better at.

“When people are married, instead of trying to get rid of each other, reflect that you have made your choice, and strive to honor and keep it, do not manifest that you have acted unwisely and say that you have made a bad choice,nor let any body know you think you have.  You made your own choice, stick to it, and strive to comfort and assist each other.”  Brigham Young, Deseret News, 29 May 1861, 98.
