Unrequited love is a paradox because it involves having strong feelings for someone who does not reciprocate those feelings. The paradox lies in the conflicting emotions of love and heartbreak experienced simultaneously by the person who is in love. This creates a situation where one's feelings are profound and genuine, yet ultimately unfulfilled.
It's perfectly possible to love someone and desire very much that this person returned your affection without that person ever actually doing so. It's unfortunate, but not a paradox.
