Overview
Unrequited love or one-sided love is love that is not openly reciprocated or understood as such by the beloved. The beloved may not be aware of the admirer's deep and pure affection, or may consciously reject it knowing that the admirer admires them. Merriam-Webster defines unrequited as "not reciprocated or returned in kind".
Psychiatrist Eric Berne states in his book Sex in Human Loving that "Some say that one-sided love is better than none, but like half a loaf of bread, it is likely to grow hard and moldy sooner." However, the philosopher Friedrich Nietzsche contends that "indispensable...to the lover is his unrequited love, which he would at no price relinquish for a state of indifference." Unrequited love stands in contrast to redamancy, the act of reciprocal love, which is the tendency for people to like others who express liking for them.
Analysis
Route to unrequited love
According to Dr. Roy Baumeister, what makes a person desirable is a complex and highly personal mix of many qualities and traits. But falling for someone who is much more desirable than oneself — whether because of physical beauty or attributes like charm, intelligence, wit or status — Baumeister calls this kind of mismatch "prone to find their love unrequited" and that such relationships are falling upward. According to some psychologists opposites do attract.
