Research indicates that while having your romantic partner as your best friend strengthens emotional bonds, it may reduce social support from other friendships, highlighting the importance of maintaining separate close relationships.

Having your romantic partner as your best friend sounds like a fairy tale, but research suggests it might not be as beneficial as it seems. A study by Colorado State University found that only 14.4% of Americans consider their partner their best friend. While this setup provides constant companionship, it may reduce social support from other friendships. Over the past decades, friendships have become increasingly important for personal fulfillment, with 60% of Americans valuing close friendships highly compared to just 23% for marriage.
The study surveyed 940 adults in the U.S., assessing relationship quality and well-being. Results showed that those who viewed their partner as their best friend reported less social support from friends, possibly due to a narrower social network. Emotional connection was stronger among partner-best friends, but social support was better when best friends were separate from romantic partners.
In conclusion, while having your partner as your best friend enhances companionship, maintaining separate close friendships is crucial for broader social support and overall well-being.
