In my opinion, it's because men are lonelier than women. Not necessarily in the sense that they have less friends but the level of commitment scales differently between men and women as opposed to the other way around. Men readily show women affection, attention and actively take interest in their lives. Women do do the same for men, but definitely on a more subdued or reduced level than men do for women. As a result, particularly for men who don't have women focusing on them, they feel lonely and want to find that connection where someone not only acknowledges their existence but actively shows interest in who they are. This isn't even necessarily a romantic thing. It often is but not always. I'd just say that men have a lot less people overall who actually care about their purpose, direction, ambition and drive as opposed to women. That's my opinion anyway.
