"From this perspective, the common experience of the fading of romance over time may have less to do with the inevitable undercutting of idealization by reality and familiarity than with the increasing danger of allowing oneself episodic, passionate idealization in a relationship that one depends on for security and predictability. Intense excitement about another is a dangerous business; it often is much safer to surrender to it with a person one cannot possibly spend much time with or will never see again. Sustaining desire for something important from someone important is the central danger of emotional life. What is so dangerous about desiring someone you have is that you can lose him or her. Desire for someone unknown and unobtainable operates as a defense against desire for someone known and obtainable, therefore capable of being lost."
