PR NEWSWIRE - Feb 7 - The second national report "The Happiness Index: Love and Relationships in America," commissioned by eharmony and conducted by Harris Interactive, shows that 83% of Americans are "happy" in their romantic relationships. Only one in nine people in a relationship are extremely or fairly unhappy. Men value happiness, physical attractiveness and health in a partner, while women find emotional and financial stability to be the most desirable. The happiest couples tend to be in love, have a healthy sex life, an equal balance of power. They're also most likely to be younger (25-44), have two kids, and are more likely to have a higher personal income of $75K+ (more than $150K combined in a relationship), and are more educated than their unhappy counterparts.
