When it comes to having a happy marriage, the husband's happiness may be most crucial in determining the health of a relationship.
A new study shows that a husband's agreeable personality and health has the strongest impact on a couple's relationship.
University of Chicago researchers found a woman's positivity had little or no effect on conflict in a marriage. But, the husband's positivity had a big effect on the relationship.
The trend was the same if one of them had poor health. The women's health had little impact on the relationship but the men's health did.
The study also finds that marital issues crop up when spouses are critical of each other, or just get under each other's skin.
