There's always going to be an instant mutual attraction when Fire sign, Aries, first meets Air sign, Gemini. According to Moore, they have so much in common like a love of excitement, variety, and adventure. "They throw themselves into the relationship enthusiastically and love each other totally, passionately and faithfully," she says. That is until the excitement wanes and boredom sets in. The issue is, both signs have an extremely low boredom threshold. "The moment problems arise (as they always do), neither has the patience to work things out so they often call it quits," she says.

When Gemini and Sagittarius get together, it's a case of opposites attracting. According to Moore, this is a "high energy partnership," where both individuals are restless and share a wide range of interests. When this couple gets together, they like to keep it light and fun. "They don't like to get too deep and meaningful, so the relationship often doesn’t progress to the next level of mutual trust and true intimacy," Moore says. They both also have short attention spans, so the relationship can fizzle out quickly.

There's a natural attraction between Cancer and Aquarius. According to Robyn, Cancer loves to nurture and Aquarius can always use a bit of nurturing. "Cancer is willing to be supportive and even entertained by the rather wacky Aquarius," she says. However, at some point, the Aquarius partner may start to feel a little tied down. When this happens, the home-loving Cancer can start to feel unloved.

The best part about a Virgo and Gemini relationship is their communication. According to Robyn, they share similar communication styles and values. They're both known for being intelligent, resourceful and practical. They can also work together to generate new ideas for creative adventures. "However, the Virgo's need to overanalyze everything will eventually drive the 'go for it' Gemini a bit crazy," she says. "The Gemini's talkative and jump-in style can leave the Virgo perfectionist exhausted."

"This is an interesting pairing," Robyn says. Leo and Capricorn will likely start out as friends. Capricorn is all about working hard and being recognized for their achievements, while Leo loves being recognized for who they are. So Capricorn can be very understanding of the Leo's need to be seen, while the Leo can be very appreciative for the support. However, things can go south when the Leo's need for attention gets a little old. "At some point the Leo wants to be worshiped, and the Capricorn will tire of just worshiping," Robyn says. The Leo can also be very supportive. But if they feel like their Capricorn partner is achieving more than them, they may start viewing them as competition and not a partner.

When a Scorpio and an Aries get together, you can expect explosive chemistry. "These two will be sexually attracted to each other initially the way that warriors bond with other warriors," Robyn says. "They'll plan adventures together and be ready to head into battle. However there can only be one leader and one winner in any battle." These two signs aren't really known for backing down. So they may battle it out until there's only one winner. As you can imagine, constant battles with your partner is not that great if you want things to last long-term.

Pisces and Sagittarius may seem so different. One is known for being very dreamy and emotionally in tune, while the other is known for being adventures and on the go. When they first meet, they can become really great friends who have really interesting conversations. However, moving beyond that can be a little tricky. "The Sagittarius may be too adventurous for the quiet Pisces, and the Pisces too subtle for the Sagittarius," Robyn says. "While the Pisces will love to hear the Sagittarius storyteller spin tales of adventure, at some point the lack of true communication will drive these two apart."

Keep in mind, there's a lot of different things that go into compatibility. For instance, Robyn says our Moon sign is very important. If your Moon sign matches your partner's Sun sign, it can be a really great match. But if you're just looking at Sun signs, every zodiac couple has it in them to make things last. These are just some pairings that may take a little more work.
