IN BRIEF: Disloyalty.

Infidelity does not consist in believing or in disbelieving: it consists in professing to believe what one does not believe. — Thomas Paine (1737-1809), American revolutionary, political philosopher & writer.

Quotes:

"Men and women are not born inconstant: they are made so by their early amorous experiences." - Andre Maurois

"A woman one loves rarely suffices for all our needs, so we deceive her with another whom we do not love." - Marcel Proust

"Every man wants a woman to appeal to his better side, his nobler instincts and his higher nature -- and another woman to help him forget them." - Helen Rowland

"No lover, if he be of good faith, and sincere, will deny he would prefer to see his mistress dead than unfaithful." - Marquis De Sade

"The hood-winked husband shows his anger, and the word jealous is flung in his face. Jealous husband equals betrayed husband. And there are women who look upon jealousy as synonymous with impotence, so that the betrayed husband can only shut his eyes, powerless in the face of such accusations." - J. August Strindberg

"You may build castles in the air, and fume, and fret, and grow thin and lean, and pale and ugly, if you please. But I tell you, no man worth having is true to his wife, or can be true to his wife, or ever was, or will be so." - Sir John Vanbrugh
