Putting this on gender is such a weird thing to do. It is just couples where one partner is intro- and the other extrovert.
Yes -- this phenomenon is somewhat gendered, but not overwhelmingly so. From the article's own statistic:
A 2025 Pew Research Center study found that 54 percent of women say they turn to a friend for emotional support but only 38 percent of men say they do.
So I think this is a problem that affects men somewhat more often than women, but happens plenty to both.
I will say that loneliness and depression go hand-in-hand. And if someone's husband is clinically depressed, that's going to look a lot like "they're not even trying."
