In talking about the silence between couples and what it communicates without words, we concluded that some of the deepest messages in a relationship are precisely the unspoken ones. But there is a moment when silence must give way to words, and that is when someone chooses to truly show themselves. That moment of disclosure, of revealing something real and fragile about yourself, is what I understand by shared vulnerability. And it is, in my view, the shortest path to authentic closeness in any relationship.

Vulnerability has a contradictory reputation. In modern motivational discourse it is almost excessively glorified. In concrete relational practice, it is systematically avoided by most people. And there is a real reason for this contradiction: talking about vulnerability is incomparably easier than living it.

What shared vulnerability actually is

Vulnerability in relationships doesn't mean crying at every sad film or expressing your emotions with an intensity the other person cannot contain. It means something more precise and more difficult: bringing into the relational space something of yourself that is real, uncertain and unprotected. Something you don't show to just anyone and which, in showing it, you accept that you can be hurt.

It might be a fear you haven't spoken aloud before. An insecurity you have been carrying in silence. A regret, a shame, a moment in which you failed and which you think about more often than you admit. A need you feel but are afraid will overwhelm the other person or make them see you differently.

Brené Brown, after years of research on vulnerability, arrived at a conclusion that initially seems counterintuitive: vulnerability is not weakness. It is the most precise indicator of the courage we have. Not the courage to do something grand in front of the world, but the inner courage to show yourself without armour in front of someone you care about.

Why vulnerability produces closeness

The mechanism through which vulnerability generates closeness is better understood today than ever before, thanks to research in social neurobiology. When someone shows themselves vulnerable to us, our nervous system responds through an activation of empathic circuits. The brain processes the other person's disclosure and, if the context is safe, responds with a reciprocal opening. This dynamic, called "reciprocal disclosure" in psychology, is one of the main pathways through which intimacy is built.

Arthur Aron, the researcher who created the experiment of the 36 questions designed to produce intimacy, demonstrated that the gradual nature of personal disclosure, one partner shows a little, the other responds with a similar disclosure, creates measurable intimacy even between strangers within hours. The mechanism isn't magic; it is structural: each act of vulnerability invites the other person to come a step closer, and the accumulated mutual closeness produces real intimacy.

What I find interesting from my own perspective is that vulnerability doesn't work unilaterally. It isn't enough for one person to show themselves. The other person also needs to receive that disclosure with care and to respond with something of their own. Vulnerability that is not well received doesn't produce closeness. It produces shame and withdrawal. That is why the way you receive someone's vulnerability is just as important as the way you offer your own.

The fear behind the refusal to be vulnerable

There is a fundamental fear that prevents vulnerability and which, once understood, becomes less paralysing: the fear that if you truly show yourself, you won't be good enough. That if the other person sees everything, including the imperfections, the fragility, the contradictions, they will find you deficient and leave or pull away.

This fear is not irrational. It is constructed from real experiences in which showing the authentic self led to rejection, to judgement or to humiliation. And once formed, it functions as a hyperreactive alarm system, signalling danger even in contexts that are, in fact, safe.

What is important to understand is that this fear, however real it is, generates exactly the opposite of what it is looking for. The person who hides in order not to be rejected ends up being accepted for a character rather than for themselves. And acceptance of the character produces a subtle form of loneliness that anyone who has lived it knows well: you are present in the relationship, perhaps even loved, but you don't feel truly seen.

Vulnerability and the context of safety

Vulnerability cannot occur in any context and with any person. And I think it is important to say this clearly, because there is a romanticisation of vulnerability that suggests total openness towards everyone is a virtue. It isn't. It is, sometimes, a lack of discernment.

Genuine vulnerability requires a context of relational safety. Meaning a relationship in which you have evidence that the other person respects what you offer them, that they don't use intimate information against you, that they respond with care rather than judgement. This safety is not assumed; it is earned over time, through repeated interactions in which you have been able to verify that the other person is trustworthy.

Being vulnerable with someone who is not ready to receive that vulnerability or who will not treat it with the appropriate respect doesn't produce closeness. It produces hurt. That is why discernment about with whom and when you choose to show yourself is a form of relational maturity, not a contradiction of the value of vulnerability.

What vulnerability looks like in practice

Vulnerability doesn't need to be dramatic or performative to be real. In fact, performative vulnerability, said with watery eyes and a trembling voice for effect, is not vulnerability; it is theatre. And people feel the difference.

Real vulnerability is often simple and even awkward. It is saying "I don't know what I'm feeling right now, but something isn't right" instead of pretending everything is fine. It is acknowledging "I'm afraid I'm not good enough at this" instead of hiding behind defensive irony. It is asking "I need you right now" instead of gesturing at independence until you exhaust yourself.

It is also acknowledging to a partner that a certain subject touches you more deeply than you want it to appear, that a certain interaction hurt you even though it's "something small," that sometimes you feel lonely even when you are together. These small disclosures, said at the right moment and received with care, are the material from which real intimacy is built.

Reciprocity as an essential element

I have already mentioned that vulnerability functions through reciprocity, but I want to insist on this point because it is frequently neglected. Relationships in which only one person is vulnerable and the other receives without offering anything of themselves produce, over time, a painful imbalance. The one who shows themselves ends up feeling exposed and alone. The one who doesn't show themselves ends up feeling distanced and unsure how to draw closer.

The reciprocity of vulnerability doesn't mean that both people open up simultaneously or in equal measure in every interaction. It means that over time, both have brought something real into the relationship. Both have shown themselves, each in their own rhythm and in their own way, and both have received with care what the other brought.

The deepest relationships I have observed, and in which I myself have felt something rare exists, have always been relationships in which both people had their scars visible to each other. Not in a metaphorical sense, but in a real one: they knew each other in the places where each had been fragile, and that knowledge had not produced distance, but a form of loyalty that nothing else can generate.

Vulnerability and individual growth

One final aspect I find important: shared vulnerability doesn't only produce closeness towards the other person. It also produces a form of personal growth. Truly showing yourself to someone who receives you well is a corrective experience in relation to all the moments when you showed yourself and were hurt. It recalibrates the belief that being seen is dangerous. And over time, this recalibration changes the relationship with yourself, not only with the other person.

Those who have allowed themselves to be vulnerable and been well received become, gradually, people less afraid of their own complexity. And people less afraid of themselves are, invariably, better partners, better friends and more complete versions of themselves.

Vulnerability is not a risk to be eliminated. It is the price of entry into real connection. And the closeness it produces cannot be obtained by any other means.

Think about the last time you showed yourself vulnerable to someone important in your life. How were you received? And if you haven't shown yourself for a long time, what is holding you back? Is the context unsafe, or is it your own fear of being seen?
