To look at infidelity from the point of view of sex is a complete narrowing of the phenomenon. There's a reason that the commandment is repeated twice in the Bible - once for doing it and once for thinking about it. We have always created structures and broken structures. It is essential to the human spirit.

Love is a vessel that contains both security and adventure, and commitment offers one of the great luxuries of life: time. Marriage is not the end of romance, it is the beginning.

Acceptance doesn't mean predictability. Sex isn't always for 11 at night - - it's also 'meet at a hotel room at noon'. What you feel during dating can exist at home, if you don't suffocate it.

In desire, there must be some small amount of tension. And that tension comes with the unknown, the unpredictable. You can close yourself off at home and say, "Whew, at last I'm in a place where I don't have to worry," or you can keep yourself open to the mystery and elusiveness of your partner.

The whole notion of one person being enough for everything gets instantly challenged when you start to talk with somebody about wanting more or of wanting something else. They take it personally, feel like a failure or feel that they lack something, so you don't talk about it because you don't want to hurt, offend, or scare the other person. You also don't want to be rejected or have them leave you, whatever the reason.

In dating, if you say no, your lover goes on to the next person. In marriage, if you say no, the person stays.

Marriage isn't meant to make you happy - it's there because it gives you a life in which you can find happiness.
