Venus-ruled Taurus is known for their stability, stubborness, and persistance. "This is the kind of sign that will wait for too long before giving up, sometimes leading them to stay in a stale and boring relationship for too long," Narayana Montúfar, senior astrologer at Astrology.com, tells Bustle. Unlike Air signs like Gemini or Aquarius, Taurus natives don't see breakups as liberating. "Because these folks take the time to 'build' the picture-perfect relationship, they see breakups as a waste of their precious time, which won’t help them get over their ex anytime soon," Montúfar says.

Cancers are known for their wide range of emotions and moods. According to Montúfar, Cancer is the zodiac sign that rules the past. So out of all the signs that make this list, they're most likely to regret a breakup. "They may beat themselves over by constantly looking at old pictures, texts, and emails to keep reviving the feeling of protection and security their ex provided them," Montúfar says. They may be a little too in their feelings to actually initiate talks of getting back together. But if you do, they'll likely be on board.

Libra is another Venus-ruled sign that tends to regret breakups. In fact, they have a tendency to avoid breakups altogether. "As the flirty, charming diplomats of the zodiac, Libras see a breakup as the ultimate failure of diplomacy, and take that very, very personally," Burns says. Since they're represented by scales and try to have balance, they tend to be very conflict-avoidant. While they come off as indecisive, they just really want to make the right choice so everything stays balanced. "Unfortunately, most people aren't willing to meet them where they are on that, so they're often left holding the emotional bag," Burns says.

Intense Scorpios are passionate, emotional, and have feelings that run pretty deep. According to Montúfar, this is a sign that will give it's all when it comes to relationships. When things come to an end, they'll be absolutely devasted. "Cautious and secretive, these aren’t the kinds of folks to jump from one relationship to the next because they invest themselves fully," she says. "Once it's over, they'll cry (Scorpio is a water sign, after all) and it will probably take them a little while to get over their ex."

Idealistic and dreamy Pisces will think about the breakup over and over again, while watching a romantic movie marathon. As Montúfar says, they're the "epitome of the hopeless romantic." If their heart is broken, they're going to go over everything that went wrong and think about all the reasons why it didn't work. If you broke up with a Pisces and decided you wanted to go after them again, they'll be into it.

So these are the zodiac signs that may not only regret a breakup, but go back to an ex. Again, Sun signs can give you a little piece of the puzzle. So if you really want to know more about someone, their birth chart can be pretty revealing.
