The Enneagram is a system made up of nine interconnected personality types that dig into our core motivations, fears, and beliefs, offering a kaleidoscopic, forensic look into the behavior and unconscious patterns that drive our decision-making.

Because of the Enneagram system's hyper-attunement to our limitations, triggers, and pitfalls, knowing your Enneagram type can help you understand how to compassionately self-manage and relate to other types. Doing Enneagram work pulls back the curtain on the inner workings of your romantic partnership and recommends a path for growth. 

"There is no such thing as a perfect Enneagram pairing," therapist Michael Shahan, LMFT, tells mbg. "Healthy people make healthy relationships."

Some research has shown Enneagram types don't affect marital satisfaction significantly. That said, there are some trends in terms of which types more commonly tend to end up together and perhaps certain traits to look for in a partner based on your type.

Type Ones are known as the Reformers of the Enneagram. Dedicated and perfectionistic, Ones are detail-oriented, conscientious individuals who have high standards. Ones are drawn to those who can help them lighten up and find beauty in the imperfect moments of life. 

In a One-Two partnership, since task-oriented Ones can feel rigid, the heart-forward and attentive Two can bring warmth to the Ones' pursuit of integrity and encourage them to soften and relax. Likewise, Ones bring consistency and security to Twos, who struggle with abandonment issues. (Ones and Twos are also Enneagram wings, which means they may have some overlapping traits.)

Type Twos are known as the Helpers of the Enneagram. Compassionate and nurturing, this self-sacrificing type can give and give to their partner until they are empty. Since Twos have a problem vocalizing their needs, it's vital they date someone who can reciprocate intimacy and won't take advantage of their generosity. 

In a Two-Three partnership, they share similar interests, energy levels, and charisma, making this a high-energy match. The charming Threes can galvanize the Twos to reach their potential instead of focusing on others, and Twos offer unconditional approval to their Three partner, who can struggle with overidentifying with their work persona instead of their authentic self.

Type Threes are known as the Achievers of the Enneagram. Driven, ambitious, persuasive, Threes are interested in excellence, crushing their goals, and reaching their ideal level of success. However, their image-oriented personality can hinder vulnerability and authenticity. 

Type Fours are known as the Individualists of the Enneagram. Self-aware, artistically inclined, and introspective, the sensitive Fours are drawn to authenticity and intensity. Fours tend to get swept away in their daydreams and feelings, which can unmoor them from reality and leave them seeking heightened emotional states. 

In a Four-Five partnership, the emotionally expressive Fours can rely on the straightforward, steady Five to say what they mean and mean what they say. The Fives' logical nature can act as an anchor to the Fours, who can feel turbulent. Fours admire that Fives are not afraid to explore the depths of emotionality and together; they can have an intense and stimulating connection. 

Type Fives are known as the Investigators of the Enneagram. Inquisitive, objective, and analytical, Fives are private, intellectual types who love learning and acquiring new knowledge. Because they are mentally focused and can live in their head, it can take Fives a longer time to process emotions and express intimacy, which can come off as detached. 

In a Five-One partnership, the Fives find value in the Ones' independence, curiosity, and similar mutual interests. Likewise, the Ones appreciate Fives' lack of judgment and steadiness which gives them comfort. The partnership can build a strong foundation of dependability and trust. 

Type Sixes are known as the Loyalists of the Enneagram. Committed and trustworthy, the security-oriented Sixes can be anxious and highly suspicious, placing value in systems and institutions to feel safe. They benefit from relationships that are calm and stable.

Type Sevens are known as the Enthusiasts of the Enneagram. Considered the jack-of-all-trades, the playful and exuberant Sevens want their life to resemble an exciting adventure, jam-packed with plans and activities. However, the Sevens are future-oriented because they are fearful of feeling the anxiety in the current moment, which can make them flighty and impulsive. 

Type Eights are known as the Challengers of the Enneagram. Powerful and self-confident, the authoritative Eights dominate their reality and express their love through protection and strength. Because they don't back away from confrontation, they can come across as forceful and overly aggressive.

Type Nines are known as the Peacemakers in the Enneagram. Reassuring and harmonious, Nines are supportive to a fault, their conflict-averse nature may cause them to minimize and simplify problems. Nines can become too comfortable, leading to stubbornness and an unwillingness to assert themselves.

In a Nine-One partnership, Ones hugely benefit from the easygoing nature of the Nine. Ones suffer from an intense inner critic, and the gentle, agreeable Nine can reduce their anxiety about always having to be right. Ones can impart structure and clarity to the peaceful Nine. 

Yes! Same-type pairings can make a beautiful partnership. "Sometimes deep similarity can be comforting or validating, and when couples find that in each other, it can work really well," Hall explains. 

While Hall observes that same-type pairings can be less common than other pairings, that might have to do with the fact that "many of us tend to find that people who are too similar to us get on our nerves."

The Enneagram personality descriptions were designed for universal application since no type is inherently masculine or feminine. However, some evidence studying married couples suggests that societal stereotypes and varying cultures can express certain gendered expectations, to the types that can influence their style of relating. 

"Some examples of this would be males who embody the nurturing, caring energy of a Two, females who are energetically dominating and move around the world as an Eight, or female Fives, who can seem distant and cut off from their emotions. This can create a lot of shame for them growing up and being told they are supposed to be a certain way," says Shahan. 

"Self-awareness comes with self-compassion. If you are not self-aware, then your personality patterns are running the show. By knowing your Enneagram number, you understand what's driving you," says Shahan. "The Enneagram is another way of making the covert overt."

It's impossible to cite one Enneagram type as good, bad, easy, or more difficult than the others (this is a common misconception about the Enneagram) because each person brings their own temperament, upbringing, and unique experiences to the table. Type compatibility is highly dependent on your and your partner's psychological maturity, which is the determining factor of the well-being of the relationship.
