"When you know, you know."

"You just haven't met the right person yet."

"When you find the one, everything will fall into place."

We hear versions of these ideas everywhere: films, songs, social media, conversations with friends.

They're meant to be reassuring.

But hidden inside them is an enormous amount of pressure.

Because if there really is a "right person", one of the most consequential questions of your life becomes:

How do you know you've found them?

The search for certainty

A recent BBC article about relationship OCD explored how particularly distressing this question can become for people experiencing obsessive-compulsive symptoms centred on their relationship.

One woman described becoming overwhelmed by sayings such as "when you know, you know" and the expectation that she should feel completely certain she had found "the one".

Relationship OCD is a real mental-health condition and deserves appropriate professional support. So leaving diagnostics and treatment considerations aside, the story raises a broader question about the way our culture talks about relationships.

Why do we expect love to come with certainty?

And why do we so often think about relationships as something we find, rather than something we build?

The soulmate model of relationships

Think about the assumptions behind the idea of "the one".

Somewhere out there is the person who is right for you.

Your job is to find them.

If you choose correctly, you've succeeded.

If you choose incorrectly, perhaps you've condemned yourself to an unhappy relationship, or eventually have to start searching again.

And somehow you're expected to know which is which.

That's an extraordinary burden to place on a decision made at one point in time.

Because people aren't static.

The person you meet at 25 won't be exactly the same person at 35, 55 or 75.

Neither will you.

Careers change.

Bodies change.

Families change.

Priorities change.

People experience grief, parenthood, illness, success, disappointment and ageing.

So perhaps the question isn't simply:

"Did I choose the right person?"

Perhaps another question matters just as much:

"What are we creating together?"

From compatibility to co-creation

Compatibility matters.

Shared values matter.

Attraction matters.

Feeling safe and respected matters.

There are also relationships that should end rather than be repaired.

But compatibility alone can't tell us what a relationship will become.

Imagine two couples who appear equally compatible when they meet.

Over the next ten years, one gradually stops asking questions about each other's inner worlds. Appreciation becomes assumed rather than expressed. Affection becomes less frequent. Life becomes logistics. New experiences disappear.

The other continues being curious.

They create rituals.

They express appreciation.

They make room for affection.

They try new things.

They support each other's growth.

Ten years later, these relationships may feel very different.

The original compatibility wasn't necessarily the difference.

What happened between them was.

Relationships are living systems

At Haven, we think about this through an idea we call Relationship Nutrition.

Your physical health isn't determined by finding the perfect meal once.

It's influenced by what you repeatedly feed your body over time.

Relationships are similar.

We believe healthy relationships need regular nourishment through seven kinds of experiences:

Curiosity. Appreciation. Growth. Affection. Presence. Rituals. Novelty.

None requires a perfect partner.

They require participation.

Ask your partner something you don't know about them.

Tell them something you appreciate.

Put your phone away and really listen.

Create a tiny ritual that belongs to the two of you.

Try something neither of you has done before.

Support something they're trying to become.

Reach for their hand.

Individually, these moments can seem insignificant.

Collectively, they're the substance from which a relationship is built.

From a fixed mindset to a growth mindset

There's another way to think about the difference.

The "right person" model can encourage a fixed mindset about relationships.

Either we're compatible or we're not.

Either the spark exists or it doesn't.

Either this is true love or it isn't.

Either they're the one or they're not.

A growth mindset asks different questions.

What haven't I discovered about you yet?

What makes you feel loved now—not five years ago?

Where have we stopped investing in our relationship?

What could we learn to do better together?

What kind of relationship do we want to create next?

Suddenly, we're not passive observers trying to determine whether our relationship passes some invisible test.

We're participants.

Love isn't certainty

Perhaps one of the most damaging expectations we've placed on romantic love is that the right relationship should eliminate doubt.

Real relationships rarely work that way.

Emotions fluctuate.

Attraction fluctuates.

Stress changes how connected we feel.

There will be mornings when your partner delights you and evenings when they irritate you.

A passing feeling isn't necessarily a verdict on an entire relationship.

And love doesn't require knowing exactly how you'll feel decades from now.

It asks something more immediate:

How are we choosing to relate to each other today?

A different question

Perhaps we should stop asking quite so often:

"Have I found the right person?"

and sometimes ask:

"Are we building the kind of relationship we both want to be in?"

The first asks us to predict a lifetime.

The second gives us something we can influence today.

You don't get complete control over whether a relationship succeeds.

No one does.

But neither are you powerless.

You can learn.

You can listen.

You can repair.

You can stay curious.

You can grow.

You can nourish the relationship.

Because perhaps great relationships aren't simply found.

They're co-created, one moment at a time.
