INFIDELITY: Will he cheat – TOP astrology aspects!

Infidelity is a deal-breaker in any normal relationship. If you want to know, whether your partner has “infidelity potential” or not, you can look into their natal chart.

INFIDELITY: Will he cheat - TOP astrology aspects!

First I would like to point out that I don’t like to make general statements in astrology since every single natal chart is different and the same aspect between two planets can play out differently in natal chart A in comparison to natal chart B.

Second, when it comes to infidelity or cheating, I do believe that this is an act of personal decision that is usually driven by complex momentary emotions. However, there can be some astrological conditions that can make someone more ‘cheatable’ or can awaken someone’s lust for cheating.

Do you want to know if infidelity can be seen in your man’s natal chart?

When it comes to astrology and infidelity, I always consider man’s Moon, Venus, Mars, and Neptune and also a condition of males 7th House (although the 5th and 8th are also playing a great role) in a natal chart.

Moon and Venus

Both planets are extremely feminine; the Moon represents feelings, and Venus is all about giving and receiving love. If they are in hard aspect to each other (square, opposition in a lesser degree) in a male’s natal chart, then he has trouble finding a balance between emotional and physical needs. These natives could have quite some trouble finding the right partner to fulfill both sides of their need so they might just simply choose to have two partners. They can be living proof of Madonna-Whore complex.

Neptune and Venus

Having Neptune (a planet of illusions and idealization) in the hard aspect with Venus (a planet of love) can lead someone to an unending search for his or her soulmate. Neptune leads to daydreaming and with Venus, this native constantly dreams about an ideal partner. However in real-life-relationships are anything but ideal, right? There can always come to conflict and we need to learn how to solve relationship problems, how to stay in a relationship and learn from it. When it comes to disagreement in a relationship people with Neptune and Venus in the hard aspect will rather choose to leave this relationship than deal with it.

Venus in Pisces

Venus in Pisces reacts similarly to Neptune-Venus’s hard aspect. People with Venus in Pisces could have tendencies to cheat, however their ‘specialty’ is that they won’t admit this to you. What makes Pisces special is that they won’t try to hurt you (I do like Pisces because of their ability to help unselfishly to other people in any situation!) and probably won’t tell you about their infidelity, however ‘when the time comes’ they will try to push you into the arms of another person so that their infidelity won’t hurt you that much. You see, they would rather see you leave them as they leave you.

Mars in fire or air signs

Mars in fire (Aries, Leo, Sagittarius) or air (Gemini, Libra, Aquarius) signs need constant stimulation or some kind of change so that things don’t get boring. Also in love – they crave excitement, and entertainment (especially true for natives who are younger than 30, who haven’t had their first Saturn Return yet). If Mars in fire sign cheats it is because an opportunity arises and he grabs it – you know, they simply hate to miss anything that could offer them extra fun or excitement. Meanwhile Mars in the air sign will probably cheat out of intellectual boredom. These natives simply need mental stimulation to keep things (relationships for that matter) fresh, and new.

7th House

This is the House of Partnerships in general so people who have Neptune (planet of illusion) or Uranus (planet that needs freedom) there, could have some difficulties when it comes to committed, long-term relationships. Neptune here gives unrealistic expectations of what a relationship should be like (any kind of relationship, not just love-related), and when a native sees that his (too high) expectations can’t be met in this relationship, he simply leaves the relationship since it becomes ‘too hard work’. With Uranus in the 7th, there is a different story. Uranus needs excitement, and a feeling of freedom, and constantly looks for ‘something new’. Relationships can easily become too boring, ‘too old’ for someone with Uranus in the 7th House so these natives constantly look for something new, even if it means outside of the relationship – do you see where I am going with this?

A list of ‘cheating’ aspects

When I was researching the natal chart of my friend’s husband-to-be and was searching for possible infidelity tendencies in his chart, I found a site with a huge list of aspects that can be listed as ‘cheating-tendencies-aspects’. I don’t know exactly where I found them, but I still have some of them saved on my computer. And here they are…

Signs of cheating in a male horoscope

• Venus as the ruler of the Ascendant (Taurus or Libra) in any aspect with Juno (orb 3°)
• Mars as the ruler of the Descendant (Aries) in any aspect with the Ascendant (orb 3°)
• Mercury as the ruler of the 8th house (Gemini or Virgo) in any aspect with the Ascendant (orb 3°)
• Venus as the ruler of the 5th house (Taurus or Libra) in any aspect with house cusps 2 and 8 (orb 3°)
• Venus as the ruler of the 8th house (Taurus or Libra) in any aspect with Juno (orb 3°)
• the ruler of the 6th house in the sign of its fall
• Venus is in the 4th Quadrant
• Mars is the first planet to rise before the Moon
• The ruler of the 7th house cusp between 22°-23° Scorpio
• The Part of Love (Ascendant + Venus – Sun) in the 1st house
• The Moon is in Aries or in Pisces
• The Moon is in the 11th House
• the ruler of the 1st house is in Aquarius
• any planet opposite the Sun

Signs of cheating in a female horoscope

• Neptune and the MC are 310°-340° apart
• Mercury and Pluto are 150°-210° apart (orb 30°)
• the Sun and the MC are 270°-290° apart
• the ruler of the Ascendant trine (120°) Uranus (orb 6°)
• the ruler of the 4th house square Neptune (orb 6°)
• the ruler of the 8th house opposite Mars (orb 6°)
• Mars in Sagittarius or Capricorn
• the ruler of the 7th house is in Capricorn
• Moon in Aries

INFIDELITY: Will he cheat - TOP astrology aspects!

At the very end…

Please, do not make any conclusion based ONLY on one single aspect. Or two or five for that matter. A few aspects are NOT enough for infidelity to occur.

For example, my close friend has a Capricorn Venus squaring her Aries Moon (You cheater, cheater, right?! Wrong!), and for a woman having the Moon in Aries, there is a ‘red-flag-warning’ that she could cheat. However, her Venus in Capricorn in conjunction with Saturn would never allow her to cheat since she yearns only for a committed, long-term relationship.

And also a synastry should be seen before making any conclusions about relationship stability.

From what I understand, infidelity is mostly associated with Uranus and Neptune aspects and transits, more specifically Sun/Uranus, Mars/Uranus, Sun/Neptune, Mars/Neptune ones. Also, Sun in Aquarius or in the 11th house, Mars in Aquarius or in the 11th house, Sun in Pisces or in the 12th house, Mars in Pisces or in the 12th house. Uranus – commitment phobia, restlessness, constantly seeking out new things, inability to form healthy, monogamous relationships. Neptune – deception, lies, foggy mind, fantasy, delusion.

I agree with you, Anna. Great insight! However, one should always take a look to “the whole picture” ergo whole natal chart before condemn someone of being a serious potential cheater.

Don’t feel paranoid. If you haven’t been given any reason to worry, just don’t worry. ❤️

However, if you want some extra advice, send me an email. ❤️

Having your Moon in Aries might be a sign of someone prone to cheating – but this has to be ‘supported’ by some other aspects, planet positions etc. as well. Aries Moon is impulsive therefore someone with this placement might act on their desires without considering the consequences, including engaging in affairs without thinking about the impact on their relationships. Also, those with their Moon in Aries might be drawn to the thrill of clandestine affairs as a way to inject excitement into their lives. However, in my observations most common reason why one with Moon in Aries would cheat, is impatience. Namely, Moon in Aries person might not be willing to work through relationship issues or communicate effectively with their partners, opting instead for the quick fix of seeking attention or affection elsewhere.
