Choosing a partner isn't only about not being alone. More than that, it's about one question: "What kind of person do I want to share my future with?"
When it comes to love, we so often act on instinct. But psychology reminds us: a happy relationship rests on clear psychological principles and real scientific evidence.
So today, let's take a more grown-up look at something worth talking through: when it comes to choosing a partner, how do you choose the right person?
1) Similar or complementary? What you actually need may be "just the right balance"
Have you noticed that we tend to be drawn to people who share our values, our daily habits — even our sense of humour?
Psychological research has found that we're usually drawn more easily to people who are "similar to us". This is known as the similarity-attraction effect, meaning that people tend to like those who share their values, interests and background, because it makes building trust easier and communication smoother (Wetzel & Insko, 1982; Montoya et al., 2008; Youyou et al., 2017).
But here's the interesting part: sometimes the differences between two people can become a source of attraction in themselves. Complementary strengths can give a relationship room to grow (Dryer & Horowitz, 1997).
For example: an impulsive person may learn to slow their pace because of a partner's composure, and grow better at thinking one step ahead before making a decision; while a spontaneous person may, within a partner's order and planning, slowly cultivate a stronger sense of direction.
Love isn't necessarily black and white. The ideal, perhaps, is "similar in values, complementary in strengths" — just the right fit.
✅ A small exercise: recognising the "attraction factors" you're looking for
- What are the 3 life values I care about most?
- Am I looking for someone "very like me"? Or someone "who helps me become better"?
- Would this kind of person support my growth and happiness in the future?
It's only by choosing consciously that we give ourselves the chance to meet the right person.
2) A considered choice? Or did you just drift into it? How a relationship begins really matters
Have you ever had an experience like this?
At first it was just chatting, a bit of flirtation, the comfort of familiar company…
And before you knew it, the two of you were together.
But psychology reminds us: "how it begins" can well shape the quality of a relationship.
The psychologist Stanley and colleagues proposed the "Deciding vs. Sliding" theory: those who "consciously, after careful thought, decide to be together" are more likely to enjoy high commitment, good communication and healthy boundaries in future; whereas those who "end up together without quite realising it" are more likely to run into ambiguous relationships, a lack of responsibility, even regret (Stanley et al., 2006).
✅ A small reminder for you:
During the flirtation stage, first ask yourself:
- Do I genuinely want to step into a relationship with this person?
- Or is it only because I'm lonely, used to them, or don't want to turn them down?
Choosing isn't settling; and love shouldn't be something you begin "by accident".
3) Looks? Credentials? Or a meeting of minds? The real key to a long-term relationship is more than you'd imagine
We're often drawn to "external conditions" such as appearance, education and income, which is perfectly normal — and a natural tendency in the course of human evolution (Buss & Barnes, 1986).
But psychology reminds us: what truly decides whether a relationship lasts has never been the credentials on a CV, but a "sense of psychological connection".
This includes:
- Sincere companionship
- Steady commitment
- Good communication
(Brackett et al., 2011; Gottman, 2018; Holmes, 1991)
If you want to find someone who can walk through the valleys with you and grow alongside you, don't stay on the surface. Spend more time understanding your partner's inner state, emotional maturity, and their attitude to life.
4) Learning to say no: love with a "sense of boundaries" lasts longer and is healthier
Have you ever had moments like these:
Choosing to stay silent so as not to upset your partner?
Quietly putting up with things to keep the peace on the surface?
Even, at times, almost forgetting where your own limits lie?
The scholar Whetstone (2024) reminds us: truly healthy love is not endless sacrifice, nor compromise that costs you yourself. A mature relationship is one in which both people can say clearly: "This is what I can accept, and this is what I can't."
Research has found that partners with a good sense of boundaries have less conflict, greater emotional satisfaction, and more stable relationships (Gottman, 2018).
✅ A "boundaries exercise" for your relationship:
- When you feel uncomfortable, try saying: "This makes me feel a little uneasy."
- When you have a need, dare to express it: "I need some space." Or "I hope we can have a proper talk."
- At the same time, respect your partner's "don't want to", "need time", and "no for now".
Speaking your true thoughts can actually make the sense of safety between you more secure.
5) Emotional maturity: when choosing a partner, the most overlooked yet most crucial condition
In love, have you ever met someone like this:
- Loses emotional control over the smallest thing
- Resorts to the silent treatment, disappears, or shifts the blame after a single argument
- Is never willing to reflect on themselves, only to blame others
Psychology tells us that this may well be a sign of insufficient emotional maturity.
People with self-awareness and a willingness to reflect usually show greater stability, communication skills and problem-solving ability in a relationship (Franzoi et al, 1985; Brackett et al., 2011; Righetti et al, 2022).
Maturity doesn't mean the other person has no flaws; it means: "When a problem arises, are they willing to face it, put it right, and grow?"
✅ When choosing a partner, pay special attention to these 3 things:
1) When pressure hits, what is your partner's emotional response?
2) Is he/she able to admit mistakes and willing to adjust their behaviour?
3) When you express a need, is your partner's attitude one of acceptance? Or of defensiveness and avoidance?
Choosing a mature person to love isn't about being picky — it's about fewer tears in the future.
✔️ A "self-awareness checklist" for choosing a partner
Before throwing yourself into a relationship, it's worth pausing, settling your mind, and asking yourself honestly:
? Do our values have enough common ground?
? Can I accept my partner's flaws, rather than holding an expectation of "changing them"?
? Does our way of communicating rest on a foundation of respect and understanding?
? Within this relationship, do I still hold on to a life and boundaries of my own?
? Is this relationship the result of careful thought and a clear-eyed choice, or just habit, dependence, or fear of being alone?
In closing: choosing the right person is also choosing a better self
Choosing a partner isn't just "finding someone for company" — it's choosing someone who can help you grow and who nourishes you, as you nourish them.
As psychology puts it: "love yourself first, then love another".
The next time you meet someone who stirs your heart, remember to ask yourself:
"Am I walking into this relationship with clarity, maturity and tenderness?"
