Aries doesn't look to cheat, but they are "full of energy and require a partner who can match them," Mckean says. A partner who doesn't seem up to Aries' speed may spark them to look elsewhere. And if they happen to find their perfect match while still in a relationship with someone else, they might not pass that opportunity up.

Taurus are not only Earth signs, they're also fixed signs. So as you would assume, it would take a great deal for a Taurus to cheat. "Infidelity of any kind is not in their nature once they commit," Mckean says. "But the key is committing. If a Taurus has cheated, most likely they weren't fully committed, something that would only be noticed in hindsight." In the rare occurrence that a Taurus cheats while they are in a committed relationship, it's because there's been some kind of distance in the relationship for a significant amount of time. In that case, if they happened to find the "right" person at the right time, they may cheat.

Geminis are known for their dualistic nature, but not all Geminis are cheaters. "Even though they're represented by the Twins and have two of everything (including partners sometimes), they only have one heart," Mckean says. Geminis love variety and intellectual stimulation. If they have a pattern of cheating, Mckean says there's likely a deeply rooted reason behind it and their partner may have unknowingly triggered it. They don't give their heart away easily, but when they do and it gets hurt or broken, they may act out by cheating. "Although they're great communicators, they may never share the true reason because it's so painful for them to remember," she says.

Cancers are naturally nurturing, and they like to be nurtured in return. For them, actions speak louder than words. Cheating doesn't come naturally for them, but if they feel neglected they can "fall into the arms of someone's affections, compliments, or compassionate ear," Mckean says. It's not something they actively seek out, but they can "accidentally" fall into it. Because of that, regularly cheating is an unlikely pattern for a Cancer, but a one-time fling isn't unheard of. "Be present and be nurturing for your Cancer and they will never stray," she says.

"Leos are fixed signs so it's more natural for them to be loyal than not," Mckean says. Although Leos love having an active social life and like being adored by many, they won't cheat on their partner because they found something better. According to Mckean, they might cheat because they weren't given enough attention in their relationship. "Leos need your keen attention to be happy," she says.

When there's not enough routine, or a lack of planning, Virgos will get out of there fast. "They aren't prone to infidelity, but if they do find solace in someone else, that person more than likely has a schedule they stick to months in advance," Mckean says. Like their fellow Earth signs, Virgos value stability. They're "naturally anxious," so knowing what to expect will give them a sense of peace. If they find someone who's consistent and has stability in their life, a Virgo can't help but be drawn in.

"Libras are romantic partners, but as a cardinal sign, they also like to have their way," Mckean says. The latter may surprise you a bit since Libras are known for being indecisive, people-pleasers. According to her, they take a long time to make decisions because they like to weight all their options. But if they find you've started to make decisions for them, it might drive them to cheat. According to Kovacs, Libras can be fickle. If treated unfairly, "they can love you one day and leave you the next."

Like the other fixed signs, Scorpios prefer having only one partner. "They also pride themselves on being able to resist even the hottest temptations," Mckean says. Scorpios take a while to fully open up to someone. So when they fall for someone, they're feelings fun deep. "If they feel their partner has become shallow [they might] be inclined to cheat," she says.

Sagittarians are all about adventure and their sense of freedom. A partner who gets super attached easily, is predictable, and stuck in their ways might bore them. Sagitarians can also be so go-with-the-flow that labels make them uncomfortable. "The outgoing centaur is unlikely to see any of their outside sexual shenanigans as cheating," Mckean says. "From their perspective, the relationship was already over the moment you asked for commitment." It doesn't necessarily mean they don't like commitment. They just need to find a partner who can keep it interesting for them and give them a sense of freedom. Defining clear boundaries over what counts as cheating and what doesn't can also be extremely helpful.

Capricorns are practical, work very hard, and like to save for the future. "When a partner isn't putting forth any effort towards their goals or if they go on a spending spree, they will cope by growing distant," Mckean says. Although a Capricorn isn't quick to physically cheat, they can become "married to an idea or their job."

Aquarians have the ability to compartmentalize. They're a fixed sign, so they like the stability of staying with one partner. But if they ever do get the urge to cheat, they might do it because they want excitement. "They [can be] surprisingly reckless when they cheat," Mckean says. Aquarians are known for seeing the world in a unique way, so their definition of cheating can differ from yours. If caught and confronted, they will immediately end their side-relationship. But if they still lack excitement from their partner, they may cheat again, Mckean says.

Pisces have a tendency to mentally escape. According to Mckean, Pisces may not physically cheat, but they are prone to emotional affairs in order to "cushion their pain when things are rocky" in their relationship. But for those who do physically cheat, they do it because they can get away with it. Luckily, she says, this is a rare kind of Pisces.

The reality is, everyone has the capacity to cheat. Just because these things can drive someone to cheat, it doesn't necessarily mean that they will. Regardless, knowing what can potentially lead someone to it can help you avoid it in your relationship.
