Nobody is waiting to get cheated on, however it happens. And Astrology can be a helpful tool in this case to keep your eyes open whether your ‘sweetheart’ really is that sweet..

There are also exceptional differences from a female to a male chart when it comes to spotting the cheating aspects in their birthchart. The aspects listed below are most common to be found in the birthchart of a cheating partner, however it may not always play out this way, depending on how the individual channels this energy within them and of how you trigger certain aspects in their birthchart.
Think about it, to someone that one dude can be an asshole, but than there is this other person whom he is devoted to for some reason.
People are permanent transits onto your life, keep this one in the back of your mind.

Useful Asteroids 

Swindle (8690) : Lies, cheating, fraud, stealing.
If this asteroid is conjunct to one of the angles, especially the ASC, you seriously got something going on there. If this asteroid makes strong aspects to Venus or Lilith, fucking RUN.

Lie (26955) : Lies, Liar.
If it’s prominent, the person has a tendency to lie. I have seen this one exact conjunct Lilith, in this case you know something nasty is going on underneath this person’s surface.

Mercury-Jupiter = Exaggerating, not fulfilling promises
Mercury-Saturn = Can bend the truth to come across as intelligent
Mercury-Uranus = Feeling misunderstood, they want truth but often act nervous
Mercury-Neptune = Confusion about truth, mentally vulnerable, lies
Mercury-Pluto = Mentally dominating, pushing ideas
Mercury-Moon = Adapt ideas, difficulty in emotional communication
Mercury-Mars = Speaking to fast and bold, speaking before thinking

The Main aspects for lying & cheating :
Neptune square Venus = Lying about money & love
Neptune square Mercury = Having own reality
Neptune square Moon = Delusional mind

12th house = Lots of planets located here in the birthchart can indicate and individual who is delusional and often has a bad relation to reality, they might not want to lie but tend to lie anyway because they often feel very misunderstood. They live mostly in their own world of fantasy and deception.

When truth comes to the surface (transits) :

• Saturn in 8th = Exposure of sexual secrets (also in retrograde)
• Pluto in 8th = Cleaning out the garbage (also in retrograde)
• Mars in 8th = Discovering secrets, tends to research
• Mars in 12th = Things might be happening behind your back
• Neptune to Venus or 7th = Being cheated on
• Saturn to Venus = Low-selfesteem, destruction resulting into cheating
• Pluto to Venus or Mars = Possessiveness, collecting partners, power struggles


 Lots of planets falling in 12th house of other person. If those planets are badly aspected than the planet person might be prone to cheating, especially when Venus, Mars or Saturn is sitting in your 12th house and receives bad aspects from your planets. There are hidden situations going on.

 A person’s 12th ruler falling in your 12th house means that the other is keeping secrets from you, but you are likely to be the one to be ‘ahead of time’ and already figured out what their secrets are. You know the secrets of your partner, but you keep their secrets secret from them 😉 I know this one is a bit tricky.
