there are plenty more fish in the sea

Etymology:

• There are other fish in the sea. There are even better ones out there. Don't be upset over what you've lost. This proverb is often used as a consolation for losing a girlfriend or a boyfriend, and has been traced back to about 1573. First attested in the United States in _Keziah_ by J. C. Lincoln, the proverb is found in varying forms: "There are plenty more fish in the sea"; "There are more fish in the sea than ever came out of it"; "The sea is full of other fish"; "There's more than one fish," etc. From _Random House Dictionary of Popular Proverbs & Sayings_ by Gregory Titelman ---------- In the mayne sea theres good stoare of fishe, And in delicate gardens ... Theres alwayes greate varietye of desirable flowers. (c1573; G. Harvey, _Letter-Book_, 1884) found here: https://www.phrases.org.uk/bulletin_board/20/messages/1232.html
