Love Compatibility: How does it work?
August 28, 2025
Can we really know if two people are compatible through a love Compatibility?
You often hear that "some signs don't go together"...
But the truth is much more nuanced.
In astrology, romantic compatibility is not just a simple Sun/Sun duo.
It's a much more subtle dance, between needs, wounds, ways of loving, conscious and unconscious expectations.
That's when synastry and the composite chart come into play.
What is romantic compatibility in astrology?
Astrological compatibility analyzes how two natal charts communicate with each other. By superimposing the two natal charts, we obtain the synastry.
In this way, we can observe how one person's planets interact with the other's.
These planetary dialogues reveal essential keys to better experiencing your relationship:
What you instinctively admire or seek in the other (even without realizing it)
The areas where you share the same desires, the same needs, the same values
The places where your energies oppose and invite you to grow together
The areas of misunderstandings, blockages, or wounds that can hinder harmony
What each person comes to awaken, work on, or transform in the other, individually.
But that's not all.
Astrology also helps to understand what each person expects from a relationship.
What each person is seeking in love, what each is willing to give, what you sometimes fear...
The key points of true romantic compatibility
Some astrological elements are essential for deciphering a relationship:
The Moon: deep emotional needs
The Moon shows what comforts you, how you react emotionally, what you need to feel good on a daily basis.
If your Moons are compatible (in similar elements for example), an intuitive understanding settles in.
If they oppose, you will need to learn to welcome the other without feeling rejected.
For example:
A Moon in Aries and a Moon in Cancer.
The first often lacks tact, a bit brusque. The second can be a bit sensitive, or emotionally unsettled when there's a lack of gentleness.
A misunderstanding can quickly arise between the two if they do not find balance elsewhere.
Venus: your way of loving
It speaks to your love language: hugs, sweet words, independence, romanticism, respecting space, capacity to express emotions...
If the Venuses get along well, love flows naturally. For example, one needs love, affection, contact while the other seeks harmony in the couple, looking for their other half, their alter ego.
Otherwise, there may be misunderstandings about how to show love. For instance, one may be very independent while the other has a maternal side that they find suffocating.
Once again, a good understanding (or not) between your Venuses cannot guarantee perfect compatibility. It is the dance of all the planets among themselves that reveals the richness, complexity, and depth of your bond.
Mars: attraction and desire
Mars shows how you act, what physically excites you.
It speaks of drive, erotic tension, and the way to take action.
Well-aligned Mars = passion.
Poorly aligned = frustration or irritation.

The Seventh House: your relationship with partnership
It's the archetype of the ideal partner that shows the type of energy you seek in the other. For example, a native with
a Seventh House in Aries will seek a confirmed, dynamic partner who challenges.
A Seventh House in Sagittarius will seek an adventurer who takes them on their expeditions.
The Lunar Nodes: soul mission of the couple
When a partner's Lunar Nodes are connected to the other's planets, it often indicates a significant encounter.
These relationships often have a sense of destiny.
They can be powerful… and sometimes destabilizing.
Composite Chart: the couple's mission
When one wants to go much deeper, the composite chart addresses even deeper questions: The couple's mission as a unit 1+1 = 1
The composite chart is a single astrological chart that represents the identity of your couple, as a complete entity. It is a wonderful astrological analysis tool for those who really want to understand the purpose of their relationship.
A powerful tool to understand:
The evolutionary purpose of the couple
The way energy flows between you two
The trials and strengths of the duo
Compatibility is not a promise of ease
Having well-aligned planets does not guarantee a simple relationship.
And having frictions in the charts does not necessarily mean failure.
What matters is the awareness that each person brings to the relationship.
Some highly compatible relationships can fall asleep, out of comfort.
Others, more "tense" astrologically, can lead to genuine personal growth.
Astrology does not say "you are made for each other." It says:
Here are the dynamics at play.
Here are the challenges.
Here are the strengths.
It's up to you!
It is good to bear in mind that no one can do the work for you.
But astrology brings you the keys to act.
To take the right direction based on what you truly desire for your couple to evolve.
Astrology to love consciously
Romantic compatibility in astrology is a tool for knowledge.
It helps shed light on what you are experiencing, to understand your reactions, to better welcome the other.
To put words to a unique, inexplicable connection.
No matter the bond you are experiencing today:
a recent encounter,
a complex love,
a soul relationship,
a twin flame
… romantic compatibility can enlighten you.
It helps to understand what you feel, what connects you and why this bond resonates so much within you.
And if you still have questions about your relationship with your partner, it may be time to explore your sky together.
