"Ruled by Mars, this sign is the warrior," Virginia Paciocco, a psychic and in-house astrologer for Spirit & Spark, tells Bustle. An Aries's hot temper and tendency to start a fight pretty quickly and easily means that in the heat of the moment, they might initiate a sudden breakup. "If they get fired up about something, they won’t hesitate to take action and move in another direction," she says. While an Aries can certainly be very loyal in a relationship, once they've decided that they want out, they're likely to move on quickly rather than draw out the process, Paciocco says.

For some folks, being in a committed relationship feels comfortable and safe, and they would love nothing more than to be able to grow old beside their partner. For others, though, this can sometimes feel stifling. "Gemini may initiate a sudden, unexpected breakup should someone more interesting come along," Barretta says. As soon as their relationship becomes pretty predictable, a Gemini is likely to get bored. While they might just want to explore a new relationship with a different partner, it's also possible that they'll decide to spend some time being single, she says.

"Cancers are one of the most emotional signs of the zodiac," Deniz Kilic, an astrologer and owner of Moonlight Astrology Boutique, tells Bustle. "They very much live in their feelings and emotions," she says. While being in touch with your feelings can definitely be a good thing, Cancers can tend to internalize these emotions, which may lead to an eruption of repressed feelings, resulting in a sudden breakup, Kilic says. If your partner is a Cancer, be intentional about giving them space to open up on a regular basis so that they don't have to feel like they need to bottle up their feelings.

The Sagittarius sign is ruled by Jupiter, which makes them the truth seeker of the zodiac, Paciocco says. "This sign loves to explore and uncover truths on [their] journey through life." While being someone who's dedicated to learning and growing is a great quality to have, this can sometimes affect the way that a Sagittarius deals with a relationship, she says. If they decide that they want to suddenly move to another country or try following another kind of lifestyle on a whim, they probably won't hesitate to follow this new path, leaving you in their wake. Since this sign focuses so deeply on the big picture, they might part ways quickly if they imagine a new life trajectory for themselves.

"Aquarius is a fixed sign, so once they make up their minds about something, they are stuck to it," Kilic says. "They approach things through their intellect more than with their emotions." This analytical approach can sometimes cause an Aquarius to end a relationship suddenly, because they dislike any kind of restraint, so if a relationship is holding them back in any way, they're not afraid to end things, she says. As independent thinkers and free spirits, this sun sign can prioritize their own freedom, so feeling stifled can prompt a breakup with little to no advance notice.

If your partner is one of these signs, that does not necessarily mean that they will break up with you without notice. Just be sure to keep the line of communication open between the two of you, so that if they feel like a problem is occurring, you can work it out together.
