" I’ve been happily married forty-eight years, and I ought to know something about it. The important thing in marriage is the relationship between two people, and when one becomes married—I mean really has become married—one has shifted the center of regard from oneself to the relationship of the two. And when you think of yourself as sacrificing or giving up things, it is not for the other person that you are doing it, it is for the relationship. And you are as much in the relationship as the other one is, do you see what I mean? This is what you are dealing with, the two together. And you have to think of yourself not as this one, but as these two as one. And I say if your marriage isn’t the highest priority in your whole life, you’re not married, that’s all. And the thing I frequently say is that marriage is not a long love affair. "
