One dominant theory would say to go by your sign’s element.

These even-tempered, patient signs are perfectly suited for a relationship built on respect and understanding.

Taurus will admire Libra’s ability to negotiate, while Libra will praise Taurus’ dependability.

The most difficult part of this relationship will be before it even begins.

With their restless and sociable natures, it can be tough for others to tell when either a Gemini or Sagittarius is interested in getting to know someone (romantically or otherwise).

Recently, one of the more popular guidelines for soulmate-hunting is to look to your “sister sign,” which is the sign directly opposite from yours on the zodiac wheel (meaning they’re six months apart).

Sister signs often have many traits in conflict, but astrologists argue that they share a unique ability to balance and complement each other.

I’m not saying you should use astrology as your sole relationship barometer, but if you’re a Leo and fall in love with a Scorpio, just don’t say I didn’t warn you. Think Britney Spears and Justin Timberlake, but exclusively that one time they coordinated those all-denim red carpet looks: unexpected, iconic and the type of thing that people model Halloween costumes after.

Aries, the ram, is famous for its passion and ambition.

They’re both super independent signs and hate to feel needy.

However, once the initial stages of mutual attraction are allowed to develop into a genuine connection, the relationship becomes a true adventure.

As a Leo, some might say I should exclusively date fellow fire signs (Aries and Sagittarius).
