Other forms: unrequitedly
Unrequited is used almost exclusively in the context of romantic love. If you love someone and they don't love you back––that, my friend, is a case of unrequited love.
Unrequited love is so painful, most people feel they are the first person in history to experience it, but the word unrequited has in fact been around since the 1520s, when it was invented, like many good words, to talk about money. It derived from re- 'back' + the Middle English quite 'pay up.'
