What Is Sternberg's Triangular Theory Of Love? A Closer Look

There's no question that a relationship will go through many phases over the years and that many emotions are involved in the development of said relationship. There are plenty of theories about the types of love and the emotions that go into it, but according to one theory, there are three main components of love. This theory is known as Sternberg's triangular theory of love.

And as a matter of fact, his theory was just proved universal through research on over 7,300 people1 across 25 countries.

In Sternberg's triangular theory of love, intimacy in a relationship deals with how close, connected, and trusting one feels toward another, Sternberg tells mbg. It also deals with communication, and namely, how well you can do it. Overall, it's about feelings of closeness and connection, or "how intimate and tied to the other person one feels," Sternberg says.

Passion, as you might have guessed, is about how passionate the relationship is. It encompasses "how excited one gets in thinking about or being with the partner," Sternberg says, or "how much one feels one absolutely needs the partner." And of course, it also deals with sexual attraction. When we have a relationship that feels electrifying and easy to obsess over, that would fall under passion, too.

The third element of the triangular theory of love is commitment, or "the extent to which one is in the relationship for good," as Sternberg explains it. And it's the only one of the three that's conscious or intentional. There is a decision component to this in the short term, which leads to long-term commitment. Sternberg describes it as "the level at which one says 'this is it; I don't need to keep looking!'" and chooses to continue the partnership.

As marriage therapist and certified sex educator Lexx Brown-James, LMFT, recently told mbg, "A relationship without intimacy and passion that solely has commitment is called empty love. These relationships can survive; however, partners might look more like roommates than lovers."

The combos people could have according to the triangular theory of love gave rise to Sternberg's idea of love as a story2, or "the idea is that we all have a set of stories of love." According to him, these ideas we have of love tell us what we think a relationship should be and thus govern how our relationships play out. "Examples of stories are the fairy-tale story, the business story, the travel story, [etc.]," he notes. "Each story has two predefined roles. For example, the roles in the fairy-tale story are a prince and a princess, and in a business story are two business partners."

To figure out which of the eight combinations you have, consider the three components and to what degree they are present in your relationship. How much intimacy, passion, and commitment is there?

There are countless theories about what constitutes love, and only you can really understand your own feelings and relationships. Sternberg's triangular theory of love, which has now been widely proved, is an excellent tool if you're looking to figure out the emotions behind your relationship and even where it may be falling short. By working to strengthen the three components of intimacy, passion, and commitment, according to this theory, your relationship will be better because of it.
