“What people look for in marriage, at least in part, is the other half of themselves. Each of us is in some measure incomplete, with some aspects of our humanity over-developed and others neglected. What we do not claim for ourselves, we look for in the other (for example, aggressiveness, tenderness, spontaneity, stability, and so on). This is most extreme in the marriages of neurotics whose own self-image is so skewed that they seek out mates who are caricatures of the other end of the personality spectrum (such as the timid, self-inhibiting woman who searches for a glamorous, super adventuresome epic-hero of a man, while he in turn seeks a woman too scared to let him get into trouble).”
