Freud wrote that love involves the undervaluation of reality and the overvaluation of the desired object. While the correct valuation of a person is an odd, if not impossible idea, we might say Freud meant something like this: for various reasons, many of them masochistic, we become involved with others who cannot possible give what we ask for; we can wait as long as we wish, but they do not have it, and one day, if we can bear to abandon our fantasy and see clearly, we might face reality straight on.
