Washington Post - Studies show that when women advance in their careers, they are more likely to divorce. So are female breadwinners. One 2020 analysis specifically examined the marriages of women in Sweden, who have more income parity than American women and more of a social safety net. It wasn’t the lack of social support that made these women divorce; it was the lack of relational support. One of the study’s authors, Johanna Rickne, a professor at Stockholm University, pointed out that men are used to being asked to fill the gap in domestic duties but not to take on more than that. It is “still seen as quite unusual for men to be the main supportive spouse in someone else’s career,” Rickne said.
