Gemini: The Master of Mental Gymnastics
When it comes to infidelity, Gemini takes the crown with nearly 31 percent having cheated or come close to cheating on a significant other. As a super-social air sign, Gemini gets bored easily and with their dual nature represented by the twins, they have enough interests and hobbies for two people—and even if one of their personalities is into monogamy, the other might not be. Gemini will cheat out of pure impulse, to let loose, out of pure boredom — they cheat because they can and they’ll justify it, telling themselves all kinds of excuses.
Their signature excuse reads like a masterclass in deflection: “It wasn’t emotional—it was just intellectual! We were debating the ethics of modern romance. Over wine. At her apartment. Twice.” Even when happy in a relationship, they fear they may miss out on the actual “one” because they’re constantly seeking to learn something new and get bored in stable relationships.
Sagittarius: The Freedom Fighter’s Favorite Justification

Sagittarius, the extroverted fire sign, is more likely to leave a relationship thinking the grass is greener on the other side, with 23 percent having cheated or come close to cheating on their partner. These fire signs are impulsive, adventurous, and reluctant to commit, and sometimes their flighty nature takes over. This sign cheats on impulse when the opportunity presents itself, when they feel suffocated or when their freedom feels compromised, quite bluntly due to a stagnant sex life.
When caught, expect to hear: “It wasn’t cheating; it was a spontaneous connection! I had to honor it. Besides, it was in another country, so technically, it doesn’t count.” The Archer is a thrill-seeker who enjoys the adventure of infidelity and will easily justify the cheating by telling themselves they needed to let loose or reconnect with some old part of themselves.
Aries: The Impulse Decision Specialist

As a competitive and dynamic fire sign, 34 percent of Aries have cheated or have come close to cheating on a significant other, acting on instinct and being most likely to stray from a relationship for a fling. As the first sign of the zodiac, Aries is extremely impulsive and has a tendency to think without acting. When Aries cheats, they’re not seeking emotional connection but rather the conquest, with their dalliances typically being impulsive one-night stands or short-lived affairs.
Their go-to excuse perfectly captures their spontaneous nature: “It wasn’t cheating; it was an impulse! I swear I was thinking about you the whole time…well, most of the time.” The Ram can fall prey to their impulses even when in love because they’re always looking for the next shiny thing, with nothing terrifying them more than routine.
Libra: The Harmony-Seeking Hypocrite

According to research, only 7 percent of Libras have considered engaging with someone other than their partner, but when they do stray, it’s particularly painful because of their contradictory nature. If a Libra cheats, it’s because they’re seeking to fulfill what they feel they’re not getting from their partner in the relationship, and they will feel horribly guilty about cheating but will do their best to hide it to keep the peace. When their partner becomes less attentive, a Libra might unconsciously seek that affection elsewhere, with their justification being seeking emotional balance and harmony, albeit at the expense of their commitment.
Their diplomatic excuse often sounds like sophisticated rationalization: they’ll claim they were simply trying to restore balance in their life or that the connection was meant to bring harmony to their existence. Libras love being in relationships so much that they often have a backup partner lined up to take over if their current relationship goes sour.
Scorpio: The Vengeful Truth-Teller

Scorpios are reluctant to let anyone in, so only 9 percent have cheated or have come close to cheating, making them one of the least likely signs to be unfaithful. However, when they do cheat, it’s often the most devastating because of their intensity. These scorpions famously hold grudges and love to get revenge, so if you cheated first, don’t be surprised if they take the low road too. Scorpio values loyalty and hates dishonesty, so they typically cheat because something is missing—usually sexual chemistry or emotional connection, and because they have a daring sexual appetite, they’ll cheat on someone they can’t be comfortable and open with.
Unlike other signs that make elaborate excuses, Scorpios are brutally honest about their motivations. Scorpio will be unfaithful if they feel hurt or suspect you of infidelity, with their vindictive spirit driving them to “settle the score” because they thrive on power and can’t help themselves. Their signature “excuse” is refreshingly direct: they’ll tell you exactly why they did it, often as a calculated response to perceived betrayal or neglect.
The Cosmic Truth About Cheating

While astrology offers fascinating insights into personality patterns, it should never be used as an excuse for cheating since each person is responsible for their own choices and actions, and people of all zodiac signs are capable of both infidelity and loyalty. The real question isn’t which sign will cheat, but rather how each sign justifies their actions when they do. Whether it’s Gemini’s intellectual rationalization or Scorpio’s vengeful honesty, these cosmic excuses reveal more about human nature than celestial influence. What would you have guessed about your own sign’s cheating style?
