Nick Cannon says he was insecure Mariah Carey was the ‘alpha’ in their marriage. He’s not the only man who’s admitted to being jealous of a partner’s success.

“I was getting mad at myself. It was like muscle atrophy,” Cannon continued. “I’m not being the dude that God put me on this earth to be.”

Cannon is far from the only man who’s admitted to being jealous of his wife’s financial status. According to “The Love Gap” by journalist Jenna Birch, there is a modern trend of straight men who claim to want partners who are intelligent, ambitious, and successful, yet decline to pursue women who demonstrate those qualities.

As Business Insider previously reported, “The Love Gap” cites a 2015 study published in the journal Personality and Social Psychology Bulletin, which found that “men rated women who were supposedly more intelligent as more desirable — except when they met the women face-to-face. Then they rated the women as less desirable.”

A 2013 study published by the American Psychological Association found a similar trend among straight men. Researchers found that male self-esteem took a hit when a female partner excelled in a task, while women’s self-esteem didn’t appear affected by their male partners’ successes or failures.

“It makes sense that a man might feel threatened if his girlfriend outperforms him in something they’re doing together, such as trying to lose weight,” said the study’s lead author, Kate Ratliff, Ph.D., of the University of Florida. “But this research found evidence that men automatically interpret a partner’s success as their own failure, even when they’re not in direct competition.”
