CERTAIN zodiac signs do feature personality factors that may put them in the cheating danger zone – so it pays to stay alert to warning signs.
But every relationship is different, and ultimately, what you and your partner make it.
Maggie Innes has decades of experience in reading the stars and has shared the six star signs that are most likely to have an affair and the red flags to look out for.
6. Aquarius
A born rebel and unconventional maverick, Aquarius may feel stifled by everyday relationship routine and can struggle with intimacy and connection.
Mind sign Aquarius requires high levels of mental stimulation and physical variety, and thrives on challenges — that they may create for themselves.
Their logical mindset can also square away infidelity as no big deal, and because they are such big thinkers, the simple pleasures of emotional or physical connection can seem less significant.

Aquarius red flags
- Cancels plans, maybe last-minute and for lame reasons
- Stops sharing innermost thoughts with you
- Something is “off” – you feel it, even if you can’t pinpoint it
5. Aries
The most impulsive and impetuous of signs, passionate Aries is prone to live for the moment, adoring illicit attractions and any chance to prove their powers of conquest.
Aries often acts before they think and are led by instinct rather than intellect.

They are the most exciting, loyal and inspiring of partners and give their absolute all to love when things are good – but can also instantly switch off the moment they stop feeling it.
A creature of extremes, all or nothing.
Aries red flags
- Usually an open book, they slam shut, become less upfront
- Normal dazzling Aries light feels dimmed
- Temper displays, snapping, mood swings – over-defensive reactions
4. Pisces
Surprised to see super-romantic Pisces in this list?
It’s this tender sign’s passion for all-consuming passion that can raise their cheating risk factor.
Pisces needs to be affirmed, adored and above all feel “seen.”
Pisces also finds it hard to express what they want or need and may expect partners simply to “know.”
If this is not happening, innate insecurity can kick in and they seek to meet their needs elsewhere.
Cheating brings terrible guilt, but this can feel like proof that forbidden love is real.
Pisces is the sign most prone to emotional infidelity rather than purely physical.
Pisces red flags
- Ghosting you – paralysed by guilt and fear of confrontation
- Hugs dry up – Pisces needs 24/7 physical contact (not just sex) but they’re pulling back rather than leaning in
- Their own betrayal makes them suspicious all round – they could seem extra jittery and jealous
3. Capricorn
Rule-follower Capricorn could never be described as a serial cheater, but if the conditions are right, eyes and heart could wander.
It’s not always easy for Capricorn to get everything they need from one relationship – partly because they find it so difficult to ask!
Bottled-up frustrations and feelings make them vulnerable, so they gravitate towards an outside lover who they feel provides what they’re missing, and flatters and pursues them.
This is a very stubborn sign, too, so a revenge affair could be a hazard.
Confrontation-phobic Capricorn could also subconsciously use cheating as a way to exit a relationship.
Capricorn red flags
- Their usual rigid schedule starts looking more erratic
- Bedtime gets a lot more interesting, as they try out techniques they’ve learned elsewhere…
- More image-conscious – working out, losing weight and dressing to impress
2. Sagittarius
Passion for freedom and quest for constant new horizons make Sagittarius a sensational partner – but this can equally be their Achilles heel when it comes to cheating.
This is not a sign that values commitment as much as others may do, and
Sagittarius is so effortlessly easy-going and sociable they might not even realise what signals they give out to potential love interests.
They live and breathe adventure and can find the prospect of exploring fresh love territory irresistible.
The archer’s honest nature can actually make them very good liars.
What is your star sign's element?
In astrology, the elements — Air, Water, Earth, and Fire signs — serve as foundational principles that influence the characteristics and behaviours associated with the twelve star signs.
Earth signs: Taurus, Virgo, and Capricorn
The Earth signs are grounded in the tangible and practical aspects of life, embodying the stable and nurturing qualities of their element. These signs are known for their pragmatism, reliability, and strong connection to the physical world, often excelling in matters that require patience and persistence.
Air Signs: Gemini, Libra, and Aquarius
The Air signs are characterised by their intellectual, communicative, and social nature. This reflects the light and dynamic essence of their elemental influence. Overall, these signs tend to excel in the realms of ideas, relationships, and innovation, bringing a breath of fresh air to their interactions and thought processes.
Water Signs: Cancer, Scorpio, and Pisces
The Water element signs are profoundly impacted by their element. With each astrological sign, water gives way to emotional depth, strong intuition, and a capacity for deep empathy and connection.
Fire Signs: Aries, Leo, and Sagittarius
Fuelled by the element of Fire, these fire signs in astrology are known for their passion, boldness, energy, enthusiasm, courage, and a zest for life that often leads them to adventurous and creative endeavours.
Sagittarius red flags
- Reluctance to lock in future plans, from date night to the holiday of a lifetime
- Mood switches – sullen instead of smiley
- Mirror obsession – constantly checking appearance
1. Gemini
The dual nature of Gemini – looking both ways at once and able to mentally compartmentalise their life into two or more very distinct parts – makes them the prime zodiac sign, on paper, to prove fidelity-lite.
Fun-loving, chatty and flirty, they are never short of options and can feel the love grass is just greener somewhere else.
Gemini needs high levels of admiration and validation and can weaken in loyalty when this comes at them full force from someone outside their relationship.
They may inwardly reason they’re just scratching an itch, and what their significant other doesn’t know, won’t hurt them.
