Every human can be guaranteed to frustrate, anger, annoy, madden, and disappoint us—and we will (without any malice) do the same to them. There can be no end to our sense of emptiness and incompleteness. This is a truth chiseled indelibly into the script of romantic life. Choosing whom to commit ourselves to is therefore merely a case of identifying a specific kind of dissatisfaction we can bear rather than an occasion to escape from grief altogether.
