H. L. Mencken

“ What women mistake for infidelity is usually no more than vanity. Every man likes to be regarded as a devil of a fellow, and particularly by his wife. On the one hand, it diverts her attention from his more genuine shortcomings, and on the other hand it increases her respect for him. ”

“ It takes more initiative and daring to start up an extra-legal affair than most men are capable of. They look and they make plans, but that is as far as they get. Another salient cause of connubial rectitude is lack of means. A mistress costs a great deal more than a wife; in the open market of the world she can get more. It is only the rare man who can conceal enough of his income from his wife to pay for a morganatic affair. ”

“ Moreover, it gives her a chance to win the sympathy of other women, and so satisfies that craving for martyrdom which is perhaps woman' s strongest characteristic. A woman who never has any chance to suspect her husband feels cheated and humiliated. ”
