A short, finished list rather than an endless feed: 4 of the best i love you quotes ever written, picked out of the full i love you archive on QuoteForever. You will find Ben Folds, Maya Angelou, Jamie Foxx and Charles M. Schulz 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.
