"There are problems connected with infidelity and problems connected with being faithful at any cost, and I am for letting those concerned choose the problems they'd prefer. There need not be one rule for all. Infidelity is enlarging and fragmenting and very very dangerous, but it has been known to retrieve people as well as marriages, so it can't be only bad. And while a lot of women would probably consider it better to have the man they care about rip-off other women if he must but hurry home again, I think I'd rather he be concerned about the survival of the people he sleeps with, even those who are not me. Men who take advantage of one woman take advantage of them all, and if he's going to have an experience in which I can't share, then I'd rather it be a good one, so if there are any benefits to trickle down the spout they'll be the kind I'd want."

“It's very important to decode your own messages, like saying "I feel angry" instead of kicking the cat, and people who learn to do this find they are misunderstood less often and, as a fringe benefit, are clawed by fewer cats.”

“It's impossible for men and women who love each other not to hurt each other now and then, but most women would settle happily for a man who tried not to cause the same hurt twice.”

“I've learned not to ask for everything, just to make sure that I get what I must have. It doesn't matter who else gets what-- it only matters if you're deprived. Really splendid men understand that and find ways to manage their lives to they never give away anything that is their wife's. And if there are times when they need more than one woman in their life, they give back what they get to both. Being faithful means not costing people you love more than they can afford to pay. The best men are committed to their partners as much as to themselves.”

“We tend to think in terms of fixing blame, of establishing adultery and making clear who did what to whom, when what is most important is not what was done but that no one be hurt. It's not that we care that much if our mate rubs off a few cells of epidermis in friction with someone else, it's that we are all afraid if he does, he'll stop loving us. And men who've always had affairs, considering it good for their morale, find that they are fearful just like their wives when the shoe is on the other foot. Any new ethic, if it's to work, will have to find ways of reconciling growth with commitment, change with loyalty, and freedom with alienation, because a world in which new loyalties constantly replace old ones will make neurotics of us all.”

“Marriages should be as diverse as the people in them are, which means that some will be one of a kind, and some totally different still. And those who don't want to love, honor and obey, should be able to promise each other anything they choose, without having to ask anyone what they think of that, particularly themselves.”

“If I had to choose between having someone physically faithful to me or having him committed to my preservation, I would opt for the latter because there is no doubt in my mind when I see couples at parties selling each other out which is the worst offense. Physical fidelity is a lovely thing if someone feels that way about you willingly, but relatively meaningless of you exact it for a price. And while it is easy enough to be faithful for the first five or ten years, it is more difficult by twice each year after that, so women as well as men are finding it hard to do.”
