While every relationship is different, mindbodygreen states that Type Ones have the best chance at a successful relationship with Type Twos and Sevens. Their reasoning? Twos help Ones love the imperfect parts of themselves, and the side-by-side types have overlapping qualities that help them understand each other on an intuitive level.
Their next pick for Ones, the Seven, makes sense because they are connected on the Enneagram chart; Type One integrates into — or exhibits growth in — a One placement, while Type Seven disintegrates into — or has a stress reaction in — Type One, per the Enneagram Institute. Seven can bring the fun and adventure to One's doorstep, while One can ground the overwhelmed Seven in their integrity and core values. The nonjudgmental Seven can remind Ones that they are more than what their inner critic tells them they are, and that letting loose on occasion is a vital part of success.
Truity boasts data collected by 88,000 participants and makes the claim that Type Ones are the most likely to stay in long-term relationships of the Enneagram types, with 38% of Ones surveyed reporting were single and 62% were paired up. Their ability to commit to and work on their relationships seems to stem from their desire for stability and predictability.
