Nobody’s standards are as high as Virgo’s: It’s perfection or bust. The practical earth sign is all about self-preservation, so they’ll do what they can to protect their energy, even if it means opting out of a relationship.

“Virgos are notoriously single because they are afraid of losing their identity in a partnership,” Desiree Roby Antila, astrologer and author of Sun Signs in Love tells Bustle. “In their heart, they would rather be alone than be with the wrong partner.”

Notoriously noncommittal, Sagittarius zodiac signs get easily restless. They need to constantly be evolving, which isn’t always convenient when in a relationship. Plus, the idea of anything serious puts off a fun-loving fire sign like Sag, so they’d rather be on their own than take on the responsibility of a relationship.

“Sagittarius is the free spirit of the zodiac, forever looking towards the expansive horizon,” explains Antila. “Being held in one place anywhere for too long goes against their philosophy of how to live life, which requires them to find a partner who gives them the freedom to broaden their horizons.”

Aquarius’ independence is extremely valuable to them. They’re content with doing things solo and prefer a life that doesn’t hinge on the expectations of a relationship. Known for being a little unorthodox, Aquarians tend to question and defy the status quo, including when it comes to love.

“Aquarius enjoys doing whatever they see fit without really needing a conventional relationship until the end of their days,” explains Antila. “With zany Uranus as their ruler, they are hard to predict and even harder to lock down. Their air element also requires someone intelligent and low-pressure.”
