Want a stronger, better relationship? Here are the 5 conversation secrets of happy couples:

  • First: They have similar speech patterns. Psychologist Dr. James Pennebaker says that couples who use the same tones, inflections, and phrases are happier than those who don't. And since similar speech patterns are the result of a couple being in sync, they're also a predictor that a relationship will last.
  • The next conversation secret of happy couples: They skip the small talk. A University of Arizona study found that the strongest couples spent no more than 10% of their time chit-chatting, while the least-happy couples discussed lighter topics almost a third of the time.
  • #3: Solid couples have their own private world. According to the Journal of Social and Personal Relationships, couples that use pet names, share private jokes, and use other "inside language" are more satisfied with their relationship than those who don't. Why? Because when you have something that only the two of you share, it creates an "us against the world" feeling, and promotes closeness.
  • And the final habit of happy couples: They say, "Thank You." Dr. Cameron Gordon is a professor of Psychology at the University of North Carolina, and his research shows that people who express gratitude toward their partners on a regular basis are happier overall.
