Strong Uranus Aspects
Aspects to look for:
- Uranus square Venus
- Uranus square Mars
- Uranus square 7th house ruler
Uranus is the planet of freedom, rebellion, unpredictability. When in hard aspect to Venus or Mars, the native craves freedom, variety, and excitement in relationships.
It is difficult for these natives to “settle down” into a “normal” relationship because of many reasons. For instance, relationships might make them feel restricted, bored, or they may constantly crave “newness” in relationships.
Its the initial feeling of getting into a relationship which excites them, so as time goes by, their interest may gradually decrease for their partner and their relationship. Bored of the everyday, “hum-drum” aspects of “regular” relationships, the house native may seek excitement outside the relationship.
Remember: Having these aspects does not guarantee someone will cheat; in some cases, it simply means they might struggle with commitment.
Strong Neptune Aspects
Aspects to look for:
- Venus in Pisces
- Neptune square Venus
- Neptune square Mars
- Neptune square 7th house ruler
With this placement, idealization of partners in common. The native has an idealistic view of relationships and love in general, and is on a constant search for their soulmate.
They daydream about their ideal mate, and the kind of relationships they envision are other-worldly. Real relationships, however, are difficult; they require a tremendous amount of work, compromise, and often include conflict.
This is the precise reason why people with these placements have such a hard time with relationships. Real relationships rarely live up to the ideal relationships they often dream about, and when confronted with these realities, the native may choose to quietly exit the relationship, leaving their partner wondering where it all went wrong.
People with these placements are attracted to the unattainable. When someone isn’t yours, it is easy to keep the fantasy of them alive because you’ll never be confronted with the realities of a real relationship with them.
This ties in to the fact they often find themselves in the role of the “other woman” or “other man”; they get all the romance and fantasy of a relationship without having to deal with the hard work that comes with it.
Similarly, Venus in Pisces natives are sometimes described as “cheaters” for the same reason; if in a relationships, the “realities” of the relationship may push them away from their mate into the arms of another.
Venus in Pisces will not be forthright about their infidelity, however; they are too concerned about hurting you to ever admit they were unfaithful. If confronted, Venus in Pisces may deny the infidelity with an innocent, “who, me?” approach. It’s rare for a Venus in Pisces to leave their mate; they’d rather you leave them than the other way around.
Strong Jupiter Placements
Look out for: Jupiter square Venus or Mars
Jupiter is the planet of expansion, excess, optimism, and pleasure. When it forms a challenging square to Venus or Mars in the natal chart, it can amplify desires, making moderation more difficult. Individuals with these aspects often have a strong appetite for romance, excitement, and physical gratification, and may be more likely to act impulsively when tempted.
Jupiter square Venus can indicate someone who loves pleasure, affection, and luxury. This aspect may lead to overindulgence in relationships, unrealistic expectations of love, or difficulty resisting romantic opportunities. If other indicators of infidelity are present in the chart, this aspect can increase the likelihood of seeking excitement or validation outside of a committed relationship.
Jupiter square Mars intensifies confidence, passion, and risk taking. These individuals often act first and think later, especially when driven by desire or excitement. They may have a strong sex drive, enjoy the thrill of the chase, and sometimes underestimate the consequences of their actions. If poorly expressed, this aspect can contribute to impulsive behavior, including sexual indiscretions.
On their own, however, neither of these aspects indicates that someone will be unfaithful. Many people with Jupiter square Venus or Mars are devoted partners who simply possess larger than life passions and desires.
Strong Gemini Placements
Gemini is a sign which craves variety and gets bored at the drop of a hat. In Venus, Gemini craves variety in relationships. This sign needs to move around, experiment, and communicate with others in order to keep itself happy.
The sign Gemini is represented by the twins, which reflects Gemini’s dual nature. Indeed, you will often find Gemini-influenced natives having at least “two” of everything.
For a Gemini Venus, this would mean having two relationships. Gemini is a mutable sign; they can adapt to different situations seamlessly, so they have the ability to flutter between two relationships with relative ease.
Venus in Gemini are big flirts; Gemini is ruled by Mercury, so they certainly have the gift of the gab and are talented at winning people over with their words.
Strong Sagittarius Placements
Sagittarius is the sign of freedom, adventure, and exploration. Individuals with strong Sagittarius energy, especially if they have the Sun, Moon, Venus, Mars, or several personal planets in Sagittarius, often crave variety, excitement, and new experiences. They tend to dislike feeling restricted or tied down by routines or controlling relationships.
In some cases, this desire for independence can make long term commitment more challenging, particularly if the individual feels trapped, bored, or emotionally confined.
However, strong Sagittarius placements do not indicate that someone will be unfaithful. Many people with prominent Sagittarius energy are loyal and honest partners who simply need relationships that allow for personal growth, trust, and independence.
Moon square Venus:
This is especially true for straight men with this aspect. JFK has this aspect, and he was known for his affairs. The Moon and Venus are feminine planets, and often play a role in the kind of partner we desire.
The Moon represents our emotions and what makes us feel secure, while Venus represents how we give and receive love. When these planets are in square aspect to one another, our emotional needs are at odds with our needs and capacity to love.
This can cause many problems, as it is difficult for the Moon square Venus native to have both needs fulfilled by just one person.
For example, say I have Moon in Aries square Venus in Capricorn: on one hand, I am emotionally fulfilled by aggressive, direct, and passionate people. However, aggression and passion to not “agree” with my Venus in Capricorn nature; it is unattractive to me, as Venus in Capricorn prefers shy, stable, drama-free mates.
Also, we can think of this in terms of synastry: if my partner’s Mars is in Capricorn, and therefore is in conjunct aspect to my Venus, I feel a tremendous sexual attraction to my partner. However, it would also mean that my partner’s Mars squares my Moon, which leads to heated arguments and hurt feelings.
As a result, the native finds it difficult to find a partner who fulfills both their Moon and Venus needs, and might choose to have two partners: one who makes them emotionally secure, and one that makes them feel loved and attracted.
This can also indicate a Madonna-Whore complex; the native may have the inability to see the partner as both a nurturing type (moon) and a sexual being (Venus). To solve this dilemma, the native may choose to take on two partners in order to have these needs fulfilled.
