Plain women are always jealous of their husbands. Beautiful women never are. They are always so occupied with being jealous of other women’s husbands
Wilde, Oscar

Among human beings jealousy ranks distinctly as a weakness; a trademark of small minds; a property of all small minds, yet a property which even the smallest is ashamed of; and when accused of its possession will lyingly deny it and resent the accusation as an insult
Twain, Mark

Instead of comparing our lot with that of those who are more fortunate than we are, we should compare it with the lot of the great majority of our fellow men. It then appears that we are among the privileged.
Keller, Helen Adams

My wife’s jealousy is getting ridiculous. The other day she looked at my calendar and wanted to know who May was
Dangerfield, Rodney

As iron is eaten by rust, so are the envious consumed by envy
Antisthenes
