Unfortunately, when it comes to astrology, there is no sign that is immune from being a cheater — each one has their shadow side, along with their positive traits. What each sign does do, however, is cheat in their own inimitable way. If you have your suspicions and want to protect yourself from a two-hearted sweetie, read on!
Aries: The Ram may stray
Another problem for Aries is that their ego needs constant stroking, making them fairly high maintenance. They fall for flattery easily, which could lead them to stray, but their short attention span means these affairs are often fleeting and meaningless. Make sure to feed them a steady stream of compliments so they know you care. Moreover, the Aries love for adventure and partying, compounded by their extreme need to be seen as the good person by absolutely everyone, could lead them to a double life. They may have "party only" friends with whom they can let their freak flag fly, but whom no one else in their social circle even knows exist.
Taurus: A practical mate with desires
This is not to say that Taurus doesn't have a romantic side. Ruled by Venus, the planet of true love, the exact opposite is true. It is just that pragmatism often wins out — at first. The heart will seek what the heart truly desires. Don't allow yourself to get swept up into Taurus' practical side, make sure to provide the tenderness and sweetness they secretly crave so they don't seek it elsewhere.
Gemini: Flirty players
While they enjoy flirty game playing, Geminis aren't on any kind of power trip. Their lovers will most likely remember them with fondness. Gemini's dual side makes them sure to choose the perfect steadfast mate for their spouse, and the perfect open-minded, up-for-anything playmate for their sidepiece. A Gemini will cheat just because they can. They probably won't even think too deeply about. Their affairs are mixture of amiable friendliness and frolic.
Cancer: Passionate affairs
Family and blissful coupledom are of utmost importance to the Cancer. To the outside world, their idyllic, extremely long-term relationships will have others seething with envy and awe. And Cancers make sure to keep up this pretense when they cheat. Cancer will often stalk out and groom their prey; they often look for vulnerable or naïve people in need of emotional support and help. The ones they cheat with and the ones they cheat on are equal victims, as they often woo their lovers with a string of lies. If you are the official partner of a cheating Cancer, do not gaslight yourself into believing "everyone cheats" or "I'm the one they really love."
Leo: Would rather quit the relationship than cheat
Leos are a sign searching for the grand, epic romance, and it can be extremely hard for them to live a life of everyday reality of lounging around the house in sweatpants watching a bland Hollywood movie after putting the dishes away. The Leo wants to live the movie, not watch it. If you want to keep your Lion happy, try to do something uniquely romantic every once in a while. It doesn't have to be expensive, just thoughtful and dazzling. Grab a boombox off eBay and stand with it held above your head while shouting out declarations of love, and your Leo will be with you for life.
Libra: Always out for true love
Librans are highly romantic so it is important you maintain an allure of sophistication and ethereal beauty, so they can continue to keep you up on a pedestal. This does not mean you must conform to society's standards, but just enjoy creating your own identity based on confidence and unique style. Even Librans in love may masochistically cheat when on a downward spiral, tearing down all the wonderful things in their world in a self-destructive act of self-pity.
Virgo: They can live a double life
Virgos can live a dual life, one of extremely focused, high achievement, defined by an almost puritanical righteousness, and another, that is definitively more louche. Virgo puts such a high price on perfectionism in all aspects of their life — marriage, home, career, family — that they can sometimes forget to just relax and let of some silly steam. Their emotional detachment causes a blind spot on the sentimental level, prohibiting them from empathizing on a feeling level with those they are close to. They can only see right and wrong from an intellectual point of view, not one of feelings, and will use pretzel logic to justify their cheating. Try to get your Virgo mate to relax and have fun so they can de-stress in a healthy way. Also, don't let them push you over the line into doing things you find intimately degrading.
Scorpio: Clingers more than cheaters
Scorpios are looking for the Bonnie to their Clyde, their ride-or-die, someone who keeps it at 100 in terms of emotional intensity and who will nurse them through their darkest moods. If you stop be any of the above, they may start to stray in order to tap into the depth of feeling again.
Sagittarius: Cheat for freedom — not for power
Sagittarians are fun, free-spirited and lacking in pretense. To be honest, they prefer to be happily single and playing the field as opposed to having a sure thing hanging on while they search for someone new. If you don't want a Sagittarius to cheat on you, then it may be a good idea to not pressure them into commitment before they are ready. When a Sagittarius cheats, it is because they are looking for the thrill of freedom, new adventures and conquests, as opposed to power, control or emotional manipulation. They will have friendly relations with their lovers that are more about fun and excitement than drippy sentimentality.
Capricorn: Often seeking status
Capricorns may cheat to let off steam and see how the other side lives. They have a tendency to cheat with the opposite of their prim and proper significant other, by seeking out someone edgy or downright trashy (by their exacting standards, that is). They will enjoy letting the mask slip and feel relief from having to constantly keep up with the Joneses and just be their unbridled, most down-and-dirty self. If you are in a relationship with a Capricorn, they will expect you to keep always being presentable and well-kept. You need to let them see the softer, more nurturing, relaxed side of life from time to time, while always keeping it classy, or you risk becoming a sort of trophy.
Aquarius: More likely to emotionally cheat than physically...
If your passionate life has dried up, the Aquarius may cheat just to get their needs met, for them it is merely finding a logical solution to a problem and not anything personal. If someone offers it up on a platter, they may take it up like someone eating a meal in a restaurant. Pleasantly indulging at the time, but when the check is paid, they will be ready to move on without any kind of emotional response whatsoever. Try to stay mentally engaged with your Aquarius through reading books and soaking up new knowledge.
Pisces: Master manipulators addicted to love
To the Pisces, love is the highest vibration of existence, and they feed off it like fuel. Anyway, anywhere, no matter who is in the way, they are after it. If it means cheating, lying, or trampling a few hearts into the ground to get who they want, it is no matter to them. Pisces often get involved with people already in a relationship, partly to puff up their ego, and partly to invoke jealousy and destroy the emotions of the person standing in the way of their heart's desire. To be honest, their conquests are often more to place themselves higher on the pecking order of desirability against other competitors than it is about the partner they have stolen. Pisces are incredible liars and, whether you are their official partner or their undercover sweetie, they will make you feel you are incredibly special and valued, all while eyeing their next potential mate. If you are with a Pisces, you need to smother them with compliments and romance to make sure their ego is sufficiently satiated.
