David Letterman has a lot to learn about being married. We all do.
Let me say first off, that I am no marriage expert and I am not judging David Letterman or his wife.
Suffice to say, perfect marriages don't exist. Marriage is often a tough relationship between two flawed people. Don't let anyone tell you that there is a perfect marriage, because short of this side of heaven, marriage is a work in progress. Even the best marriages have their moments of failure, doubts, disagreements, etc.
So what about Letterman? Here is my advice to the late night comic:
Being married is not akin to having an affair. Toss out the jokes. The loser in all of this is your young son, Harry. Be a man Mr. Letterman. Admit your mistakes and seriously repair the relationship (if she will let you) with your son's mother...
