Before “What’s your sign?” was a dumb cliche, it was an effective pick-up line. That’s because it was once common wisdom that those born under certain star signs are more compatible with certain others. That theory has fallen out of fashion, but we’ve dug through the archives to find out what they wisdom of yesteryear has to tell us about our romantic lives today. Here are the best combinations of zodiac signs for a long, happy relationship:

Scorpio and Cancer

This passionate pair will bring a strong balance of hard work and adventure. The Scorpio will bring intense loyalty, which the Cancer will appreciate, but the crab will keep things fresh and unpredictable.

Beware of other Scorpios who may try to disrupt the good thing you’ve got going. When Scorpios go bad, they can’t stand to see those who share their star signs living the good life. Some of the more twisted Scorpios out there might try to steal your partner away just to prove they can do it.

Aries and Gemini

This is another balanced pair. While the Aries will be goal-oriented and decisive, the Gemini will make sure that they don’t get tunnel vision by pursuing their folly. If the ram can get the twins on board with a common goal, the sky’s the limit.

In order to make it to the altar, though, you’ll both have to work on the challenges that haunt your signs. Aries can get impatient sometimes, so that’s something to watch out for. Gemini can be a bit high-strung, which will activate the Aries’ impatience. If you’re a Gemini, work on mindfulness and a calm spirit to keep your romance going strong.

Sagittarius and Leo

These two were made for one another. Each may be a little hot-tempered and reckless, but they both tend to favor positivity and kindness. This mirrored personalities can really feed off of one another. Things may get heated between these two fire signs, but that can be a good thing—especially in the bedroom.

Threats to the relationship include the Sagittarius habit of failing to see potential problems until it’s too late, and Leo’s tendency to get a bit bossy. Keep the lines of communication open, even if that means the occasional squabble, and you’ll be together forever.

Libra and Aries

Talk about power couples! This tandem brings diplomacy and leadership together. Both of these signs will work hard to get a task completed—that can mean that when they work together, both can look forward to attaining high degrees of achievement at the personal, social, and professional levels.

However, those born under the sign of Aries aren’t known for their meticulous planning. Don’t let your impulsiveness threaten the good thing you’ve got going with that Libra. As for the Libra side of this partnership, watch your naturally flirtatious manner. Don’t make the Aries in your life jealous.

Pisces and Scorpio

The fish and the scorpion go together like yin and yang. While Pisces can cool things down with their reserved and occasionally spacey demeanor, the Scorpio will bring intensity and dedication to the table. When these two get together, they balance out perfectly.

On the other hand, if you’re not careful, this pairing can lead to a power imbalance in which the Scorpio seizes too much control over the Pisces’ life. Proceed with caution and compassion to keep things going good.

Virgo and Aquarius

When these signs pair up, it can be pure bliss. An Aquarius will constantly be bringing new ideas to the table and the Virgo will analyze the heck out of all of those thoughts, thinking through the finer details while their partner has moved onto the next big idea. These two complement each other cerebrally, too, as when the water bearer wants to be alone, the metaphorical maiden can keep herself perfectly occupied with her thoughts.

Your main relationship hurdle will be balancing the Aquarius’ love of experimentation with the Virgo’s critical, perfectionist nature. Learn to cooperate and you’ll have a romance for the ages.

Aries and Capricorn

This is another powerful pair; both are ambitious and active, but they each bring a different leadership style to the table, helping one another to keep all four of their eyes on the prizes. Whether they’re looking to host a party or conquer the world, if they decide to do it together, this couple can make it happen.

This tremendous pairing implodes when Capricorns develop a pervasive negative bias toward the world at large, which is something they’re predisposed to do. If you’re the Aries in the relationship, remember to point out unwarranted negativity to keep your partner looking forward and upward.

Pisces and Cancer

The fish and the crab work together passionately. The Cancer brings a fresh, romantic perspective and the Pisces will soak it right up, appreciating every gesture of love and respect.

To get the most out of this relationship, the Pisces will have to overcome a habit of keeping secrets. The Cancer must remember not to overreact. Master these life skills and you’ll be well on your way to the perfect love affair.

Gemini and Virgo

This mindful match can really work well together, seeing every side of a problem, meaning that they can work their way through anything. With their powers combined, there are few things that can’t be made better.

If you find yourself in a Virgo–Gemini relationship, you both need to take a deep breath before you respond during a disagreement. When this pair gets into an argument, they may say things they don’t mean, expanding a minor squabble into a major, relationship-threatening battle.

Capricorn and Aquarius

Here you have a combination of the leader and the thinker. One can be developing a plan while the other is actively implementing, meaning that, together, these two get stuff done.

Unfortunately, Capricorns and Aquariuses are both subject to fits of depression. You have two choices about how to deal with it when one of you falls deep into the dumps. You can either work together, relying on your own experiences to help your partner emerge from the darkness, or you can follow them into that bleak state of mind. Discuss your plans when you’re both in good moods so that you’re ready for the inevitable crash.

Taurus and Virgo

This is one of the most stable, long-term-friendly pairings that the universe makes available. The Taurus is a delightful homebody, someone who would rather spend the evening with Netflix and a loved one than out at the club.

The Virgo also prefers to stay at home. Social anxiety is a typical trait from this star sign. As a result, people in these relationships are great geniuses of the “staycation.”

This strength is also their greatest potential weakness. Constant proximity can make you forget what it’s like to be out in the world, making new friends. That sets the stage for one of Taurus’ most unfortunate attributes: a tendency toward jealousy.

Sagittarius and Taurus

Everyone knows that people born under the sign of Sagittarius love travel, adventure, and a free spirit. Meanwhile, most folks born under Taurus prefer the comforts of hearth and home. How can these two make a great couple?

It’s all about the yin and the yang. It’s hard for many long-term relationships to last, but there’s an exception for Sagittarius-Taurus couples. Out of all the zodiac combinations, a link between a Sagittarius and a Taurus is the most powerful.

The challenge for the Taurus will be giving the Sagittarius the complete freedom they require. For the Sagittarius, it’s important to remember how much you care for your partner, and to be grateful for the relationship in your life. Don’t let a sudden whimsy make you forget who you’re really with.
