When it comes to the question of how to make relationships last, most people would answer with “love,” “trust,” or maybe “understanding.” While all of these components are necessary for a healthy, long-lasting relationship, it’s a lot more complex.

One professor was so curious about what makes relationships last that he analyzed over 1,000 studies to uncover the answers. Brian Ogolsky, an associate professor in human development and family studies at the University of Illinois Urbana-Champaign, analyzed all studies published since the 1950s about “relationship maintenance,” and then listed the most commonly cited strategies for making things work.

“Relationship scientists spend a large proportion of their time predicting why people break up and some of the more negative sides of things,” says Ogolsky, “and I really wanted to dedicate my career to understanding the positive sides of relationship as much as possible.”

He and his team sorted through the studies for two years and noticed a few common themes among the data. First, people used two different techniques to keep their relationships afloat: 1) stopping it from ending, and 2) nurturing the relationship. Couples also used techniques to avoid breaking up, such as making sacrifices and forgiving each other after a fight.

Ogolsky realized that in relationships, individuals and couples keep the bond strong because each contributes to the relationship differently. With those things in mind, let’s determine what keeps relationships alive! We’ll break it up into what couples and individuals do.

Here are 17 things that make relationships last, according to research:

What individuals do to avoid breaking up:

how to make relationship last

1. Ignore other potential partners:

People in a happy, healthy relationship tend to not pay attention to what else is out there. “Half of it could actually be I think that guy’s ugly,” says Ogolsky, “and another is actually trying to turn that off, and not attending to that guy at all.”

2. Think their partner and relationship is the best:

Partners often idealize their other half by thinking they are smarter or hotter than they really are, or thinking their relationship stands out in some way. Most couples like to believe that their connection is special, hence the reasoning to stay in the relationship. If either partner stops believing this, “the writing is on the wall,” says Ogolsky. The belief that your relationship is above average motivates you to stay in it.

3. Paint mistakes in a positive light:

People in relationships try to think of the positives when their partner does something hurtful. “For example if your partner cheats on you, you can make an number of attributions about that,” says Ogolsky. “You could say ‘My partner is a dirtbag and I really hate him. He’ll probably do that again.’” If the conclusion is the latter, then the relationship will likely fail. Sometimes, people give their partner the benefit of the doubt, he points out: “You could reinterpret it as that he’d made a mistake and it was one-time thing.”

What couples do to avoid breaking up:

1. Deal with conflict:

Couples who stay together for long manage conflicts by compromising, apologizing, or agreeing to disagree. Those who don’t engage with their partner or give the silent treatment have a much lower chance of making things work.

2. Forgive:

The concept of forgiveness is important to any relationship. But, Ogolsky says, forgiving too much can actually put a relationship on the rocks. “If you’re a constant forgiver, there comes a point where it’s not great for your relationship because someone is taking advantage of you,” he says. “That can actually erode mental health.” Being a doormat in a relationship only leads to resentment.

3. Sacrifice:

The decision “to forgo self-interest and desired activities for the good of a partner or relationship is an important aspect of maintaining relationships,” according to the research. But, Ogolsky says, this concept is a two-way street. “We want some balance in sacrifice. People don’t like to over-benefit in a relationship, either.”

4. Be there for each other:

In research terms, this is called “facilitation.” This includes anything your partner may need help with, such as time management or completing a project. Helping each other out helps to strengthen the relationship bond and make larger goals come to life.

5. Be each other’s stress reliever:

Rather than adding to the stress, couples that stay together attempt to reach a solution or simply provide comfort and support for their partner.

What individuals do to improve the partnership:

1. View the relationship as a team:

Once in the relationship, people who think of themselves as one team rather than two individuals last longer. Additionally, says Ogolsky “spending your own time thinking about your relationship,” will keep things going. “It can be spending time thinking about partner, it can be reminiscing, it can be thinking about the things you’re going to do.”

2. Show generosity:

This means “any random act of kindness toward your partner,” says Ogolsky. Examples of this would be taking out the trash when it isn’t your turn, or making dinner for your partner after a long day.

3. Express thanks:

Gratitude for both the relationship and partner have been shown to strengthen the bond between couples. However, this also has to be a two-way street.

4. Pray for their partner:

You might not think of this as a common way to make relationships last, but several peer-reviewed studies published in renowned journals suggest that prayer keeps relationships going. “The guys who are doing this work are pretty well-known in the relationship realm and are not at religious institutions,” says Ogolsky. “If you’ve had asked me what I thought about this five years ago, I would have said ‘ah no.’ This is not one of the things I would have ever thought would have been quite as robust as it is.” Praying may help the person engaging in the act think more lovingly toward their partner, because they want what is best for them and hope it comes their way.

What couples do in relationships that last:

1. Communicate effectively:

This means that every day, couples strive to listen to and understand their partner while communicating their needs. This includes “being positive, being open, providing partners with some assurance you’ll be around, splitting labor in the household and doing it together,” says Ogolsky. Yes, that means washing dishes from time to time.

2. Talk about their relationship:

Couples who plan to stay together for a long time discuss their relationship. They talk about any problems they’re having, what their plans are for the future, and how they think they’re doing in the present.

3. Actively listen:

This differs from #1 in that couples have to make sure not just to hear their partner, but listen.  When one person speaks, this means the other person needs to put down whatever they’re doing and give their partner their full attention.

4. Make each other laugh:

People who use humor often have a better chance of staying together. “It’s not about a funniness gradient,” says Ogolsky, “but whether or not that’s one of the tools in your tool bag that you pull out typically during stress. Those who demonstrate humor have a way of defusing the situation and making it easier to handle.” However, hurtful humor such as sarcasm and mocking can put a big dent in the relationship.

5. Plan fun things together:

A couple that never hangs out or enjoys their time together won’t last long. Being in a relationship requires both people to care about whether the other is having fun and doing things that make them happy. “Engaging in leisure activities with a partner is theorized to increase communication, define roles, and increase marital satisfaction when leisure satisfaction is high or when partners are positive and have strong social skills,” says the study. Having a good time with your partner is good for both of you.

Ogolsky stresses that his findings aren’t a one-size-fits-all prescription for success but rather, a research tool that couples might use as a reference. This is partly because most of the studies he and his team analyzed used college students, which means the same strategies may not translate into the real world.

However, since these techniques have worked in over 1,000 studies, you might want to try them in your relationship!
