“This principle - that your spouse should be capable of becoming your best friend - is a game changer when you address the question of compatibility in a prospective spouse. If you think of marriage largely in terms of erotic love, then compatibility means sexual chemistry and appeal. If you think of marriage largely as a way to move into the kind of social status in life you desire, then compatibility means being part of the desired social class, and perhaps common tastes and aspirations for lifestyle. The problem with these factors is that they are not durable. Physical attractiveness will wane, no matter how hard you work to delay its departure. And socio-economic status unfortunately can change almost overnight. When people think they have found compatibility based on these things, they often make the painful discovery that they have built their relationship on unstable ground. A woman 'lets herself go' or a man loses his job, and the compatibility foundation falls apart.”

“What counts in making a happy marriage is not so much how compatible you are but how you deal with incompatibility.”

“I have known many happy marriages, but never a compatible one. The whole aim of marriage is to fight through and survive the instant when incompatibility becomes unquestionable. For a man and a woman, as such, are incompatible.”

“And what is the right woman, the right man? Someone who wants to go in the same direction as you do, someone who is compatible with your views and your values-- emotionally, physically, economically, spiritually.”

“I think they have compatible silences.”

“As a rabbi, I’ve spent long hours counseling people I’ve married, and in each case I like to talk with the couple about not only compatibility and love, but also their relationship with money. If you and your partner are not in the same financial mind-frame, then chances are your marriage won’t work. You can’t be an army of one when you are married. Financial problems are the number one cause of divorce.”
