My word of the day is unrequited.
The word unrequited describes a feeling, especially love, not returned.
Synonyms: unreciprocated, unreturned, spurned, rejected, unsatisfied.
Usage in a sentence: “It was an unrequited, one-sided romance, that ended in rejection”.
Interesting fact: Hans Christian Andersen is known as someone who suffered from unrequited love. A woman named Riborg was an unrequited love of Andersen’s. A small pouch containing a long letter from her was found on Andersen’s chest when he died, several decades after he first fell in love with her, and was rejected.
