Nobody has higher expectations than Virgo; it's either perfect or don't try. The practical earth sign is all about protecting oneself,
therefore they'll take any steps necessary to do so, even if it means walking away from a relationship.
According to Desiree Roby Antila, astrologer and author of Sun Signs In Love, "Virgos are notoriously single because they are terrified of losing their uniqueness in a partnership."
Sagittarius zodiac signs are notoriously apathetic and often fidgety. They must continually change, which is not always practical in a partnership.
A fun-loving fire sign like Sag is also turned off by the prospect of anything serious, thus they would rather be single than take on the responsibilities of a committed partnership.
Independence is incredibly important to the Aquarius. They seek a life that is independent of romantic expectations and are happy to go it alone.
Known for being a touch unconventional, Aquarians frequently challenge and question the status quo, even when it comes to romantic relationships.
Since they don't really need a traditional partnership till the end of their lives, Aquarius enjoys living their lives as they please, according to Antila.
