One of the most curious things I encountered in selecting the quotes below was their remarkable inconsistency. At times I even found them sharply contradictory. No surprise, really. For there are few subjects as peculiarly subjective, or ambiguous, as love in general—and unrequited love in particular. Which explains why the tone of these quotes ranges from bitterness and cynicism to the most heart-rending melancholy and despair. Unquestionably, there are few experiences more painful than realizing that the person for whom you have such adoring sentiments doesn't, can't, or won't return your so-committed, so-impassioned feelings.
