The Romantic vision of marriage stresses the importance of finding the “right” person, which is taken to mean someone in sympathy with the raft of our interests and values. There is no such person over the long term. We are too varied and peculiar. There cannot be lasting congruence. The partner truly best suited to us is not the one who miraculously happens to share every taste but the one who can negotiate differences in taste with intelligence and good grace. Rather than some notional idea of perfect complementarity, it is the capacity to tolerate dissimilarity that is the true marker of the “right” person. Compatibility is an achievement of love; it shouldn’t be its precondition.
