The Fire Sign That Can’t Commit: Sagittarius

Picture this: your Sagittarius partner comes home from a weekend trip with that guilty look in their eyes and a story about “finding themselves.” Ranked at first place on the scoundrel scale is fire sign Sagittarius, with 16 per cent of Gleeden members born between November 23rd and December 21st. This isn’t just some random dating app drama either – we’re talking about a massive study of over two million members from a site that specializes in extramarital affairs.
The passionate and rebellious personality traits encompassed by this centaur sign supposedly means a Sag’s is more likely to fall into traps of temptation. Their excuse game is legendary though. Signature excuse: “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.” When confronted about their wandering ways, these archers will swear they were just following their adventurous spirit and exploring life’s infinite possibilities.
The Master of Dual Lives: Gemini

The second sneakiest sign is Gemini with 14 per cent of Gleeden members born between May 21st and June 21st. But here’s where it gets wild – Gemini doesn’t even see it as cheating half the time. These social butterflies are so naturally flirtatious that they genuinely believe they’re just being friendly when they’re actually crossing major boundaries.
Here’s the thing about Geminis: they’re not cheating because they don’t care – they’re cheating because they care…about everyone. These social butterflies love a good chat, and sometimes that chat turns into, “Oops, I fell into someone else’s arms!” It’s not betrayal to them; it’s networking. Their go-to excuse? “It wasn’t emotional – it was just intellectual! We were debating the ethics of modern romance. Over wine. At her apartment. Twice.” They’ll genuinely believe this nonsense too.
The Impulsive Heart-Breaker: Aries

And the third star sign most likely to be unfaithful is Aries, with 13 per cent of Gleenden members noting a birthday between March 20th and April 20th. These ram-headed fire signs don’t plan their affairs – they stumble into them like a bull in a china shop. An Aries is a spontaneous and impulsive sign that loathes routine. The findings suggest in order to to spice up their lives an Aries could turn on the charm for some extramarital action.
Aries doesn’t plan to cheat; it just kind of…happens. Their favorite excuse is pure Aries gold: “It wasn’t cheating; it was an impulse! I swear I was thinking about you the whole time…well, most of the time.” They’ll stand there with that sheepish grin, acting like their inability to control themselves is somehow endearing rather than devastating.
The Romance Addict: Libra

Depending on where you look, Libra takes the top spot when it comes to cheating. In fact, research shows that Libra and Gemini – both of which are air signs – tend to be in competition for who is the most likely to be unfaithful. A survey by Illicit Encounters found that Libras have a 16% chance of cheating and Geminis have a 14% chance, per The Hits. These Venus-ruled romantics are absolutely addicted to love, attention, and being adored.
Libras are ruled by Venus, which makes them natural romantics. Think: candlelit dinners, whispered poetry, and those eyes that look like they’ve seen right into your soul. But here’s the kicker: they’ll look into everyone else’s soul too. Libras hate conflict and love being adored, so they’ll avoid telling you the truth if it might hurt your feelings – or make them look bad. Their excuse arsenal includes claiming they were just being “friendly” or that they “didn’t want to hurt anyone’s feelings” by rejecting advances. Classic Libra – always trying to keep everyone happy, even when they’re destroying relationships.
The Intellectual Cheater: Aquarius

According to Gleeden’s members other notable signs partial to a bit of infidelity include Aquarians (12 per cent), Capricorns (nine per cent) and Cancers (eight per cent) Don’t sleep on Aquarius though – they might not top the charts, but their approach to infidelity is uniquely infuriating. These water bearers will intellectualize their way out of any accountability.
Aquarius doesn’t cheat because they’re bored – they cheat because they’re curious. “What if I didn’t conform to society’s outdated relationship norms?” they ponder as they “accidentally” grab coffee with their coworker. Their signature move? “I didn’t cheat – I was just exploring new dimensions of love! You should really read the article I sent you about polyamory last week.” They’ll bombard you with philosophical arguments about the nature of love and commitment, all while completely sidestepping the fact that they broke your heart.
The Scientific Truth Behind Zodiac Cheating

Recent studies reveal that 50-60% of married men engage in extramarital sex at some time or another during their relationship (Atwood & Schwartz, 2002 – Journal of Couple & Relationship Therapy, Volume 1, 2002 – Issue 3)! In our opinion the percentage is (much) higher (at least 60%-70%)! But here’s the thing about astrological research – it’s not exactly peer-reviewed science. A qualitative study of more than two million members of dating websites was conducted by Gleeden, a site specialising in extramarital affairs, to determine which zodiac signs were more likely to cheat on their partner. They indicated Sagittarius rates with the highest reports of infidelity from all zodiac signs. This was followed closely by Gemini that was reported as the sneakiest star sign and those to be the highest in flirting.
The patterns are fascinating though. “Sagittarius, Gemini, Aries and Aquarius are called masculine signs: they are active and have an outgoing personality.” These signs share certain traits that seem to correlate with unfaithful behavior – they’re adventurous, social, and crave novelty. But remember, correlation doesn’t equal causation, and plenty of people from these signs are completely faithful partners.
Why These Signs Struggle with Fidelity

Let’s dig deeper into the psychology here. While they are known for their charm, wit, and adaptability, their restless nature can sometimes lead them to seek excitement outside of committed relationships. Their innate curiosity and need for stimulation may make them more susceptible to temptation. It’s not that these signs are inherently evil – they’re just wired differently when it comes to relationships.
They dislike the mundane and have a love of adventure and new experiences, and often crave freedom as opposed to being tied to one person. The same can go for Mars in either of these signs as well. For fire signs like Aries and Sagittarius, the thrill of the chase and new experiences can override their commitment to one person. Air signs like Gemini and Aquarius get bored easily and need constant mental stimulation – sometimes from multiple sources.
The Real Reasons People Cheat

According to a 2020 study published in the Journal of Sex & Marital Therapy, people who had cheated cited anger at their partner, low self-esteem or low commitment, feeling unloved or neglected, a need for sexual variety or a waning sexual desire, or circumstance. The latter of which were attributed to being intoxicated or feeling stressed out. This research shows that infidelity is way more complex than just your birthday.
Statistics say 44% of men report cheating on their partner because they wanted more sex – and excitement was reported to be a powerful motivation. 40% of women reported cheating for emotional reasons, such as needing attention or wanting to feel desired. Statistics say 33% cheated on their partner to find out if they were still desirable. And get this – 11% of surveyed women cheated as revenge. The motivations run deep and have nothing to do with the stars.
How to Spot a Cheating Partner

Birth charts of those who are serial cheaters typically contain a hard Neptune aspect. Not only is Neptune the planet of illusion, delusion and confusion, it also rules secrets and lies. Neptune is a complex planet, but it’s usually there when cheating is involved. But you don’t need to be an astrologer to recognize the warning signs.
Look for sudden changes in behavior, secretive phone use, and those gut feelings that something’s off. As far as asking the question goes I don’t need to ask, because I trust my intuition more these days than in the days of being played. I know if i get 3 of Swords when I do tarot, I am being a sucker again. Knowing the answer to those harder questions like compatibility and will we end up together takes more skill and is why we pay a professional to do it instead of ourselves. Trust your instincts – they’re usually right.
The Age Factor in Infidelity

Men in their 60s report having a higher rate of infidelity (24%), with the number still increasing until ages 70-79, with 26% of men cheating on their partners. Women, on the other hand, have the highest rate of infidelity in their 60s (16%), but the number goes down as they approach their 70s (13%) and 80s (6%). This completely destroys the myth that cheating is just a young person’s game.
In recent years we are seeing more adults cheat into their 50s and their 60s. The highest infidelity is in men 60-69 years of age, though just a decade ago, the highest infidelity was among men in their 50s. For women, their highest infidelity rates happen at 50-59 years, whereas a decade ago, the same was true of women in their 40s. Midlife crises are real, and they don’t care about your zodiac sign.
Modern Cheating Goes Digital

According to a study in Computers in Human Behaviour, 18% to 25% of Tinder users are in a committed relationship while using the app. When looking at Americans only –this amount skyrocketed to 42% admitting to being married or in a committed relationship while using Tinder. The digital age has made cheating easier than ever, regardless of what constellation you were born under.
Studies show 10% of adults in a relationship find their partners online using websites such as Ashley Madison. Not only are people finding partners to cheat with online, but some are also engaged in cybersex video chat rooms. Your Sagittarius ex might blame the stars for their wandering eye, but the real culprit is probably their smartphone and lack of self-control.
The Bottom Line on Zodiac Infidelity

It can’t be stated enough that these are possibilities and not something that’s definitive or based in science. Of course, anyone can cheat for any reason, and in many of those cases, it’s not necessarily linked to an astrological sign. The research shows clear patterns, but remember – you’re dating a person, not a zodiac sign.
Sure, astrology gives us some hilarious insights, but cheating isn’t about star signs – it’s about choices. Still, if you’ve ever dated one of these signs, you’re probably nodding along, sipping your coffee, and thinking, Why is this so accurate? The truth is, we’re all a little messy when it comes to love. But hey, next time you’re swiping, maybe check their birthday. Just to be safe. And whatever you do, don’t date someone whose Venus is in Gemini – you deserve better.
