A short, finished list rather than an endless feed: 74 of the best jealousy quotes ever written, picked out of the full jealousy archive on QuoteForever. You will find Ovid, Virginia Woolf, Luc De Clapiers and Gina Barreca among them.
Read the list top to bottom, or use it as a starting point - every author name links to everything else they said, and every quote has its own page you can share or turn into an image.
