'How happy a woman believes her marriage is has a direct impact on the quality of her husband's life, according to research in the Journal of Marriage and Family. And that holds "no matter how he feels about their nuptials."

“I think it comes down to the fact that when a wife is satisfied with the marriage she tends to do a lot more for her husband, which has a positive effect on his life,” said Deborah Carr, a professor in the Department of Sociology, School of Arts and Science at Rutgers University, in a written statement. ”Men tend to be less vocal about their relationships and their level of marital unhappiness might not be translated to their wives.”

An individual's own degree of marital satisfaction is "a sizable and significant correlate of life satisfaction and momentary happiness" for both genders.

"However, the association between husband's marital quality and life satisfaction is buoyed when his wife also reports a happy marriage, yet flattened when his wife reports low marital quality," the study said.'
