The Chemistry That Can’t Last Forever
Remember the beginning?
The racing heart when they walked into the room. The way conversations stretched into the early hours without either of you noticing the time. The sense that you’d found someone who finally, completely understood you. The feeling that this – this – was different.
That intoxicating state has a name: limerence. Psychologist Dorothy Tennov coined the term in 1979 to describe the intense, involuntary experience of “falling in love” – characterised by obsessive thinking, emotional dependency, and the overwhelming desire for reciprocation.
Here’s what neuroscience has since revealed: limerence is a neurochemical event. Your brain floods with dopamine, noradrenaline, and phenylethylamine – the same chemicals involved in addiction. You’re not imagining that you feel high. You literally are.
And like any high, it can’t be sustained.
The Inevitable Transition
Research suggests limerence typically lasts 6 to 18 months – sometimes up to three years in the right conditions. But nature tends toward homeostasis. The neurochemical cocktail cannot be maintained indefinitely. Your brain, quite sensibly, returns to baseline.
This is where many couples panic.
“The spark is gone.”
“We’ve grown apart.”
“I love them, but I’m not in love with them anymore.”
These phrases reflect a fundamental misunderstanding: that the fading of limerence means something has gone wrong. That real love should feel like the beginning forever. That if it doesn’t, the relationship has failed.
Imago Relationship Therapy offers a radically different interpretation: When limerence fades, you’re not falling out of love. You’re being invited into a deeper kind of love.
The Three Stages Every Relationship Travels
Harville Hendrix and Helen LaKelly Hunt, founders of Imago therapy, describe three natural stages of intimate relationship:
Stage One: Romantic Love
This is the limerence phase – neurochemically driven, fantasy-fuelled, unconsciously purposeful. Your “old brain” has found someone who matches your internal image (your “Imago”) of your early caregivers. The chemistry signals: This person can give you what you’ve always needed.
The experience is real. But it’s also temporary – and, in important ways, unconscious. You’re “loving under the influence.”
Stage Two: The Power Struggle
As the chemicals fade, reality emerges. Your partner is not, it turns out, a perfect mirror of your needs. They have their own wounds, their own defenses, their own limitations. And – this is the painful part – they often wound you in the same places you were wounded in childhood.
This is not a sign that you chose wrong. It’s actually what’s supposed to happen.
Hendrix puts it simply: “Conflict is growth trying to happen.”
The power struggle is where most couples get stuck. They oscillate between hot conflict and cold distance. They wonder if they married the wrong person. They consider leaving.
Stage Three: Conscious Love
The third stage doesn’t happen automatically. It requires intention, skill, and courage. But when couples make this transition, they discover something remarkable: a love that is deeper, more stable, and ultimately more satisfying than the neurochemical high of the beginning.
Real love needs the light of consciousness. It cannot develop during romantic love (which is unconscious) or during the power struggle (which is reactive). It emerges when partners choose – deliberately, repeatedly – to become healing resources for each other.
Why the Power Struggle Is Actually Good News
Here’s the paradox at the heart of Imago therapy: you were unconsciously drawn to someone who would wound you in familiar ways.
Not because you’re masochistic. Because you’re trying to heal.
Your “old brain” doesn’t seek a partner who will keep you comfortable. It seeks a partner who will give you the opportunity to complete unfinished business from childhood. The very traits that trigger you most in your partner are often connected to your deepest unmet needs.
This explains why couples who “seem so different” ended up together. This explains why your partner’s specific behaviours get under your skin in ways no one else’s do. This explains why conflict keeps circling the same themes.
The power struggle isn’t evidence that you chose wrong. It’s evidence that you chose exactly right – for growth.
The question is whether you’ll use that opportunity or run from it.
What the Research Shows About Long-Term Love
Here’s encouraging news: couples who stay together and do the work report that love gets better, not worse.
Helen Fisher’s brain imaging studies found something remarkable. When researchers scanned the brains of couples married 21+ years who reported still being deeply in love, they found similar activation in the reward centres (ventral tegmental area) as newly-in-love couples – plus additional activation in regions associated with calm, security, and maternal attachment.
Long-term love, it turns out, retains the passion while adding depth.
Paul Amato’s 20-year longitudinal study found that for couples who stay together, satisfaction doesn’t decline – it follows a U-shape, often returning to newlywed levels. A 2021 meta-analysis of 165,000 participants found that relationship satisfaction increases between ages 40 and 65.
Couples married 35+ years describe their love as “less turbulent but more stable, secure, and deeply satisfying.” They’ve moved from reactive to intentional, from chemistry to choice.
From Falling to Standing
The shift from Stage Two to Stage Three requires a fundamental reorientation:
From passive to active. Romantic love happens to you. Conscious love is something you do. As Hendrix writes: “Love is a behaviour, not a feeling. It is something you DO.”
From fantasy to reality. You stop relating to your projection of who your partner should be and start seeing who they actually are – a separate person with their own history, wounds, and needs.
From reactivity to intentionality. Instead of defending against old wounds, you learn to respond from the present moment. You choose curiosity over criticism, connection over control.
From me-focus to we-focus. You begin caring for the “Space-Between” – the relational field you create together – as much as you care for yourself.
This transition doesn’t happen through willpower alone. It requires new skills: how to dialogue without defending, how to validate without agreeing, how to empathise even when triggered. These are learnable. But they must be learned.
The Practice of Conscious Love
What do couples in Stage Three actually do differently?
They maintain the 5:1 ratio. John Gottman’s research shows stable couples have at least five positive interactions for every negative one. They’re generous with appreciation, affection, and attention – not because they feel like it, but because they’ve chosen to prioritise the relationship’s emotional bank account.
They repair quickly. They don’t let ruptures fester. When disconnection happens – and it will – they move toward each other rather than away.
They respond to bids. Gottman found that couples who stayed together responded to each other’s “bids for connection” 86% of the time. A bid might be a comment, a question, a touch, a look. Conscious couples learn to notice and respond.
They stretch. Imago therapy calls this giving your partner what they need even when it’s hard for you. The behaviours that are most difficult for you to give are often the ones your partner most needs – and paradoxically, the ones that will most heal you.
The Invitation of Valentine’s Month
If you’re reading this and recognising the power struggle in your own relationship – the repetitive conflicts, the distance, the sense that the magic has faded – know this: you’re not broken. You’re in transition.
The question isn’t whether you can get back to the beginning. You can’t – and you wouldn’t want to, because limerence was beautiful but also blind.
The question is whether you’ll move forward into something better: a conscious partnership where love is built deliberately, where conflict becomes growth, where you become healing resources for each other.
This doesn’t happen by accident. It happens through intention, skill, and supported practice.
The Intensive Path
Our three-day Imago Couples Intensive is designed specifically for this transition. It’s not about rescuing failing relationships – though it serves that purpose too. It’s about teaching couples to love consciously.
In three focused days, you learn the dialogue skills that transform conflict into connection. You understand each other’s worlds – the childhood wounds, the unmet needs, the defensive patterns – in a way that creates compassion rather than blame. You design practical behaviours that build safety and passion into your daily life.
Couples who complete intensives often say they accomplished in a weekend what would have taken months of weekly sessions. That’s because transformation happens in immersion.
This Valentine’s, you have a choice. You can give each other another dinner, another gift, another gesture that will be forgotten by March. Or you can give each other the skills to stand in love – consciously, intentionally, for all the years to come.
Book your Imago Couples Intensive and discover what lies beyond the power struggle: real love, built together.
