Human beings are hardwired to pair-bond and most people have experienced some of the social pressures to find a life partner and start a family but a new study suggested while romantic relationships are important, friendships also play a key role in our happiness.

Natalie Pennington, assistant professor of communication studies at Colorado State University, and a team of researchers surveyed 940 American adults. She said fewer people call their romantic partner their best friend than you might expect.

"Only about 14.4 percent of the sample said 'this is my romantic partner and it's my best friend.'" Pennington reported. "It raises that question of how much pressure we're putting on that romantic relationship."

People surveyed who saw their partners as their best friends said they felt closer to them and interacted with them more often than those whose best friends were not their romantic partners. But Pennington noted those whose best friends were not their partners reported greater feelings of social support. The study was published in the Journal of Social and Personal Relationships.

Pennington pointed out as people get older, they are more likely to call their romantic partner their best friend, in part due to social networks tending to shrink over time. She added having multiple people you can lean on, and help support, can be a challenge.

"Because you've got to maintain several different types of relationships, different degrees of closeness," Pennington explained. "When you have more people, that means that you have greater opportunity to get different types of support, different types of feedback, learn from each other."

For people still looking for a romantic partner or a friend, Pennington suggested starting small. She stressed communication is a lot like exercise. Talking to people more often helps stretch and strengthen that socializing muscle.

"Talk to the barista as you order a coffee. Turn and chat to somebody on the bus or the train," Pennington advised. "When we take those little actions to start talking to strangers, and getting a little bit more comfortable and confident socializing, it can really help us grow our relationships."
