But if men aren’t vulnerable in close relationships, where does their vulnerability go? An adage we learned in graduate school is “women internalize; men externalize.” In broad strokes (and with exceptions), this means that when upset, women go inward, blaming themselves and feeling guilty and depressed. But men, instead, express their upset through how they interact with the world. This is evidenced by a study that found that women are more likely to suppress their anger, whereas men are more likely to act aggressively. They might yell, bully, punch a wall.
