Marriage Often Ends in Ambivalence Before It Ends in Conflict

Saturday, April 25, 2026.

There is a romantic superstition—one of many—that successful relationships depend mainly on intensity of feeling.

How much do you love your partner?

How attracted are you?

How devoted?

Reasonable questions.

But possibly, the wrong questions.

A fascinating new study by Rasheedah Adisa and Andrew Luttrell in the Journal of Social and Personal Relationships suggests something stranger may matter alongside love itself: how certain you are about what you feel.

That sounds abstract until you recognize it.

Two spouses may both say they love one another.

One says it with settled conviction.

The other says it with a tremor.

Same words.

Different marriage.

In my couples therapy experience, I have sometimes suspected relationships do not begin unraveling when affection disappears, but earlier, when confidence in affection becomes unstable.

When admiration gets interrupted by chronic grievance.

When attention drifts elsewhere.

When the bond no longer feels epistemically secure.

This newer research hints that intuition may have empirical footing.

And if so, it changes how we think about commitment, doubt, infidelity, and emotional safety.

Because perhaps marriages do not often die from conflict.

Perhaps they erode first through ambivalence.

And ambivalence, unlike conflict, often whispers.

What the Research Found

Adisa and Luttrell examined not simply whether people held positive attitudes toward their partners, but how certain they felt about those attitudes.

Participants who reported both positive feelings toward their partners and greater certainty about those feelings reported higher relationship satisfaction and better mental well-being. Their feelings also changed less over time.

That last point matters.

Certainty did not just correlate with happiness.

It appeared related to durability.

And, intriguingly, the effect was strongest in relationships longer than twelve years.

Not twelve months.

Twelve years.

Which suggests certainty may matter most precisely when novelty has worn off and love has become something more disciplined than spontaneous.

That sounds suspiciously like marriage.

What Is Relational Certainty?

I want to push beyond the study’s phrase attitude certainty and propose something broader: relational certainty.

Relational certainty is not simply being sure you love your partner.

It is confidence in the continuity, reliability, and meaning of the bond itself.

It includes:

• confidence your partner’s goodwill is durable.

• confidence conflict does not automatically threaten attachment.

• confidence positive meaning can survive scrutiny.

• confidence the relationship remains interpretable as fundamentally safe.

That is much larger than liking your spouse.

It may be to adult pair bonding what felt security is to child attachment.

And if that is true, this is not a minor research finding.

It is a potentially neglected organizing variable in relationship science.

Love Versus Confidence in Love

Love is one thing.

Confidence in love is another.

One concerns emotion.

The other concerns metacognition—the mind’s confidence in its own emotional stance.

It is the difference between:

I love my partner.

and

I trust the durability of my love for my partner.

Those are cousins, not twins.

And in long relationships, that second sentence may quietly govern much more.

Including resilience.

Including repair.

Possibly even including fidelity.

The Missing Variable in Attachment Theory

This overlaps powerfully with John Bowlby’s foundational attachment theory and Sue Johnson’s later research showing secure bonding depends less on conflict absence than on reliable emotional responsiveness.

Secure attachment has never meant mere affection.

It has meant reliable expectation.

Confidence the bond holds.

Confidence the other returns.

Confidence one can lean.

In other words—certainty.

Attachment theorists call this felt security.

I wonder whether part of felt security is really certainty about positive relational meaning.

Not:

Does my partner love me?

But:

Can I rely on the continuity of that love?

That is a deeper question.

And often the one distressed couples are actually asking.

Epistemic Safety in Relationships

By epistemic safety, I mean the felt legitimacy and stability of your experience inside the relationship—the sense that the goodness of the bond does not require constant re-litigation.

A sense that the goodness of the bond does not require constant re-litigation.

That one’s positive reading of the relationship is stable enough to be inhabited.

Its loss often produces what many couples experience as vague relational dread.

Nothing dramatic has happened.

No affair.

No explosion.

Yet something feels less anchored.

Often what has weakened is not love itself.

But certainty in the meaning of love.

That matters.

Because uncertainty is psychologically expensive.

It breeds surveillance.

Interpretive trespassing.

Digital jealousy.

Demand-withdraw cycles.

The whole carnival.

Is Certainty Just Another Word for Fondness and Admiration?

Not quite.

Admiration may help produce certainty.

But certainty appears broader.

Admiration concerns valuing a partner.

Certainty concerns confidence in the durability and interpretability of the bond itself.

That is not the same thing.

In fact, one might argue admiration is one pathway through which relational certainty is maintained.

Admiration Is Not a Feeling

John Gottman’s work on fondness and admiration has long suggested admiration protects relationships.

But admiration is often misunderstood as sentiment.

It is not.

It is attentional discipline.

It is what happens when partners continue noticing what remains worthy.

And I suspect that practice stabilizes certainty.

Repeated admiration may make positive attitudes toward a partner feel less revisable.

That would fit this research beautifully.

And it helps explain why certainty mattered especially in long unions.

Long love runs less on intoxication.

More on cultivated regard.

The Quiet Panic of “I Love You, But I’m No Longer Sure”

There is a sentence therapists hear that sounds ordinary but often signals danger.

“I love them, but I’m not sure what I feel anymore.”

Notice the fracture.

Love remains.

Certainty does not.

And sometimes the second loss is more consequential.

People often assume doubt means love has died.

Not always.

Sometimes doubt means love has lost coherence.

Different problem.

Potentially repairable.

The Heresy: Maybe Affairs Begin in Uncertainty

This is speculative.

But clinically plausible.

Affairs are often framed as failures of desire or morality.

Sometimes they may begin as failures of certainty.

When conviction in the primary bond weakens, alternatives gain psychic brightness.

Caryl Rusbult’s investment model taught us commitment rests partly on satisfaction, investments, and perceived alternatives.

This newer certainty research may suggest a metacognitive layer operating beneath those variables.

That could matter enormously.

Because perhaps some betrayals begin not when love disappears.

But when certainty thins.

Attention Drift May Be How Certainty Erodes

Here I want to be more explicit.

I suspect attention drift may be the mechanism through which certainty weakens.

Repeated inattunement may not simply create hurt.

It may destabilize the partner’s positive internal model.

Missed bids.

Half-listening.

attention split across digital micro-attachments.

Sex without presence.

Emotional outsourcing elsewhere.

The thousand migrations of attention.

These may not merely reduce intimacy.

They may quietly reduce conviction.

And long before couples say, “I think I’ve fallen out of love,” they may have already stopped trusting the durability of love.

That is a different phenomenon.

And perhaps a deeper one.

Attention Is the Primary Currency of Intimacy

Certainty does not arise in a vacuum.

It is fed.

Or starved.

Repeatedly.

Missed bids.

Half-listening.

Phones at dinner.

Sex without presence.

Emotional outsourcing elsewhere.

The thousand migrations of attention.

These may erode certainty long before they erode declared commitment.

Which is why relationships often appear intact until suddenly they do not.

The erosion was subterranean.

Only the collapse looked sudden.

When Doubt Is Not the Opposite of Love

Doubt is often portrayed as love’s saboteur.

Sometimes it is love’s examiner.

Reflective doubt can refine commitment.

It can expose complacency.

It can demand truth.

And sometimes uncertainty is not pathology at all.

It is discernment waking up.

Sometimes Doubt Is Wisdom

A bad marriage can produce certainty too.

Terrible certainty.

The certainty your needs will be mocked.

The certainty tenderness will not be reciprocated.

The certainty honesty will be punished.

So let us not romanticize certainty.

Sometimes uncertainty is not pathology.

It is perception waking up.

Someone says:

“I’m no longer sure this relationship is good for me.”

That may not be ambivalence.

That may be discernment.

One destabilizes love.

The other protects the self.

Those are opposites.

Can Certainty Be Rebuilt?

I think so.

Though not through reassurance-seeking.

That often worsens it.

Certainty is rebuilt through repeated experiences that restore coherent positive meaning.

Repair attempts.

Responsive attention.

Admiration practices.

Conflict that ends in understanding.

Behavior that makes trust reasonable again.

Certainty is not merely believed.

It is enacted into existence.

That distinction matters.

The Couples Therapy Implication

Of course, certainty may not simply cause relationship satisfaction; satisfying relationships may themselves generate certainty. That possibility deserves humility.

This research suggests couples therapy should not only ask:

How much love remains?

But:

How stable does love feel to each partner?

That is a different assessment.

And one many therapists neglect.

Because people can report decent affection while privately experiencing collapsing certainty.

That may be the deeper emergency.

And often the less obvious one.

Romantic Indifference Revisited

I have argued elsewhere that relationships often do not die in explosions.

They die in indifference.

This research offers a refinement.

Perhaps indifference is not merely low passion.

Perhaps it is advanced certainty erosion.

A quiet collapse in confidence that the bond carries living meaning.

That feels clinically true to me.

And if true, it means the earliest warning signs of relational decline may be epistemic before they are behavioral.

That is a very different theory of marital deterioration.

Signs Certainty in a Relationship May Be Eroding

• You revisit whether you love your partner during ordinary conflict.

• Positive interpretations feel harder to access.

• Admiration is replaced by chronic audit.

• Alternatives feel unusually vivid.

• Emotional undecidedness persists even in calm moments.

• You no longer assume goodwill without evidence.

Most marriages do not collapse in dramatic revelations.

They thin out in private revisions.

A spouse stops assuming goodness.

Stops assuming return.

Stops assuming “we” survives strain.

Long before people leave each other, they often begin editing each other downward.

Love often survives periods of low passion.

It has a harder time surviving sustained interpretive doubt.

That is often how certainty dies.

FAQ

Is uncertainty in a long marriage always a red flag?

No. Some uncertainty reflects reflection, fatigue, developmental change, or unresolved conflict. The question is whether uncertainty leads toward curiosity and repair or toward detachment and drift.

Can certainty be rebuilt after betrayal?

Often yes, but rarely through reassurance alone. It is rebuilt through repeated trustworthy action, emotional responsiveness, and restored epistemic safety.

Is certainty just another word for commitment?

No. A person may remain committed while privately uncertain. The distinction matters.

Can too much certainty be unhealthy?

Absolutely. Rigid certainty can mask denial, trauma bonding, or constraint commitment.

Does declining certainty predict affairs?

We do not yet know empirically. But I suspect it may function as an early vulnerability marker.

The Brain Hates Unstable Love

A brief speculative note.

Contemporary predictive processing models suggest the mind constantly builds models to reduce uncertainty.

Stable love may function partly as one such model.

When a bond becomes chronically ambiguous, the psyche may experience something like persistent prediction error.

That may be one reason relational uncertainty feels so agitating.

The brain dislikes unstable realities.

Especially intimate ones.

Final Thoughts

We have spent decades asking whether couples feel enough love.

Perhaps we should also ask whether they trust the continuity of love.

Those are not the same question.

And marriages may depend more on the second than we have recognized.

Most relationship advice tells couples to keep the spark alive.

This research whispers something else.

Keep conviction alive.

Passion fluctuates.

Conviction carries.

And maybe lasting marriages are less often destroyed by loss of love than by erosion in confidence that love is still there.

That is a different diagnosis.

Possibly a truer one.

When Reading About Relationships Isn’t Enough

People often arrive here the way most of us arrive anywhere on the internet: after typing a question into Google they would rather not ask out loud.

Sometimes what looks like relationship confusion is not confusion at all, but erosion in certainty that something precious still has a stable center.

That deserves attention.

If you are finding your relationship caught in one of these patterns, you may not need years of therapy to shift it. Many couples benefit from focused, science-based intensives that compress months of work into a few days.

If you’re reading this out of curiosity, keep going.

If you’re reading this because something in your relationship is actively slipping—pay attention to what comes next.

This is where couples usually wait too long.
