So they will do anything they can to protect their energies, even if it means rejecting a romantic partnership.
"Virgos are notoriously unmarried because they fear losing their personality in a relationship,"
Sagittarius zodiac signs are notoriously indecisive and frequently restless. They must continually change, which is not always convenient in a relationship.
"Sagittarius is the free spirit of the zodiac, always looking toward the vast horizon."
"Being trapped in a same location for too long goes against their life philosophy, thus they must choose a spouse who allows them the freedom to widen their horizons."
