There's no perfect formula for a happy relationship, but science has gotten pretty close. According to Business Insider, psychologists have found that successful relationships have a lot in common. For instance, studies have shown that the happiest couples have sex once a week, and enthusiastically support each other in their endeavors. And how couples start tough conversations can determine the success of their relationships. If a couple handles conflict with empathy and kindness from the start, it's a sign that their marriage is built to last. Also, couples who share the same drinking habits are more satisfied in their relationships. Finally, couples that are the most successful are those who are able to focus less on the pursuit of money and possessions--and more on each other.
