Hello, partner. Say, have you ever been divorced?
I believe in trying to do whatever you can to save the marriage, but sometimes personalities clash and incompatibility results in divorce. 
So no more till death do us part. You marry someone, then your personalities clash and you are no longer compatible. Seems a cop out to me.
Well, to answer your first question, I have been married for 21 years and never divorced, but I agree with you, people often "cop out".

Divorce, in my opinion, if often more difficult that working on the marriage with alimony, child custody, child visitation, distribution of property...etc.

You—and you alone—have always been the only thing I wanted, and now that you are gone, I have no desire to find another. Till death do us part, we whispered in the church, and I have come to believe that the words will ring true until the day finally comes when I, too, am taken from this world.
