Sure it does. But it doesn't make the news very often. It's not the sensationalism that the media seems to crave. Harmonious marriages are not the norm projected to society. Soap operas portray marriage as something no more serious than a child's first crush.
Characters are married five or more times.
Which may be okay for a make believe world, but in reality, a broken marriage, means broken hearts. There are certain unspoken rules that most happy couples abide by. One of the most important is, they have the ability to laugh at themselves. Laughter can dismantle many a time bomb. They respect each other and know not to hit below the belt.
