The fiery first sign of the zodiac is described as bold, spontaneous, passionate, and determined. When you’re number one, like Aries, you expect nothing less than the best, especially when it comes to finding a romantic partner. While the ram has many admirers and compatible zodiac matches, there are only three zodiac signs that are most likely to be Aries’ soulmates. So, whether you’re an Aries yourself or have a crush on one, astrologer Clarisse Monahan reveals which signs can capture and hold their attention long term.

According to Monahan, the zodiac signs that are most compatible with Aries share a few key characteristics. For starters, they are usually direct and honest about what they want and need. While Aries are competitive, they do not engage in relationship games. They’ll be able to relax their guard once they know what someone wants from them. Aries also expects their partner to be loyal and free, which all three signs can provide. “Anyone who lets Aries be themselves and doesn’t get in the way of their dreams is essential,” Monahan says.

Leo (from July 23 to August 22)

When these two Fire signs come together, they both light up and fuel the other. They trine each other in astrology, which means they share the same sensitivities and outlook on life, according to Monahan. They can easily handle each other’s passionate and wild sides, and they feel very free and relaxed around each other. One disadvantage is that both Aries and Leo can be a little self-centered, which can lead to butting heads. Ultimately, this couple can overcome any obstacle because they have a deep understanding of one another.

Scorpio (October 23 – November 21) is a fixed sign.

Scorpio and Aries may appear to be strange bedfellows, but they are both ruled by Mars, the planet of war, action, and desire. According to Monahan, Scorpio requires passion in all aspects of their lives, and Aries thrives on it. “Scorpio expects love to transform them, for better or worse,” she says, “and Aries finds this energy endearing, passionate, and difficult to resist.” One disadvantage of this pairing is that both signs are easily envious. They can easily get caught up in a never-ending cycle of heated arguments followed by makeup sex if there isn’t a strong foundation of trust.

Aquarius (20 January — 18 February)

Aquarius is known for being cold and emotionally detached, but in astrology, they also represent hopes and dreams, according to Monahan. These Air signs are often romantic, optimistic, and yearn for that deep connection. It’s difficult for them to find the right person to invest their energy in — until they meet Aries. “Aquarius appreciates Aries’ honesty and directness, and Aries appreciates Aquarius’ unique and honest approach to dating,” Monahan says. “Both signs sextile each other, which is a very harmonious aspect in astrology, implying compatibility.” While both signs are highly independent, Aries’ possessive nature may push Aquarius to seek greater freedom. Aside from that, the two share a great deal of respect, fascination, and mutual admiration.
