If you take a “glass half full” look at relationship statistics, 60 percent of people who get married stay that way. Here are 4 ways to help make sure you’re part of that 60 percent: 

  • Use terms of endearment. A study in the Journal of Social and Personal Relationships found that the more pet names a couple has for each another, the higher their level of marital satisfaction. That’s because pet names are something only the two of you share, which helps you feel bonded.

  • Successful couples have hobbies in common. Dr. Howard Markman is with the Center for Marital and Family Studies at the University of Denver. And his research shows that the amount of time partners spend engaged in pleasant activities is one of the biggest predictors of marital success. And it can be as simple as cooking together. Dr. Markman says, time spent doing things together, is an "investment in the relationship"

  • They stay connected to their parents. Relationship expert Dr. Jane Greer says that when couples feel like they’re part of an extended family, they’re less likely to split up. But there’s one exception – the couple shouldn’t turn to their family first in times of happiness or sadness. Those things should be shared with your partner first. 

  • Successful couples take "for better or for worse" seriously. Dr. Thomas Bradbury is a professor of clinical psychology at UCLA. And he says that when the going gets tough, couples that stay together act like a team. They don’t say, “How could you let that happen?" when a spouse loses a job. Couples who survive don’t do things that increase their partner's suffering. They take on problems with a team mentality – so each person feels like there’s always someone who has their back.
