I once sat across a friend who had that unmistakable post-date glow—the one where pupils dilate, voice softens, and rational thought takes a leave of absence. She said, “I think I’m in love.” I smiled, because I’ve said that too, and later realised I might’ve just been in a biological sugar rush. Love and hormones—what a conniving pair. One wears perfume, the other carries science; together, they convince us we’ve found “the one”.
But how do you know the difference? Let’s take a slow walk through the brain, the heart, and all that sits trembling in between.
The Brain’s Conspiracy
When we “fall”, the brain releases a heady mix of dopamine, oxytocin, and norepinephrine. In plain English: joy, attachment, and obsession. The effect feels spiritual. You think of the person constantly. You replay texts as if decoding scripture. You lose appetite, or suddenly eat like it’s your last meal. The brain behaves like it’s discovered a drug—because it has.
Psychologists call this stage limerence. It’s the phase where attraction mimics addiction. Your prefrontal cortex (the part that makes wise decisions) takes a nap, and the limbic system (emotional centre) throws a rave. In that moment, you’re not necessarily in love; you’re chemically intoxicated. It’s nature’s way of ensuring we pair up long enough to reproduce, or at least attempt to.
The irony? This surge of hormones is meant to fade. Usually within 6 to 12 months, the body downshifts, and what remains is either love—or disappointment.
The Transition from Fireworks to Fireplace
Real love begins after the hormonal fireworks die down. When you can look at the person without the cinematic haze and still feel safe, seen, and calm—that’s when something deeper might be forming. The shift is subtle but profound. The relationship stops feeling like a chase and starts feeling like home.
Once the dopamine rush steadies, oxytocin and vasopressin take over—the bonding chemicals. These promote long-term attachment, care, and stability. If you still want to reach for their hand even when they annoy you, that’s chemistry evolving into connection.
The psychological shift here is from fantasy to familiarity. Love becomes a choice rather than an impulse. It’s no longer about butterflies; it’s about belonging.
Society’s Obsession with the “High”
We live in a culture addicted to the first 90 days of romance. Songs, films, even social media captions glorify that early intensity—”the spark”. But no one writes love songs about the Tuesday nights of companionship or the quiet mutual growth that sustains a relationship long after hormones have cooled.
It’s not our fault entirely. We’ve been sold a cinematic version of love that thrives on dopamine: the chase, the uncertainty, the drama. Real love, though, is quieter. It doesn’t make for viral reels. It doesn’t scream; it stays.
The problem arises when people confuse the hormonal comedown for boredom. They think, “The spark’s gone, so maybe this isn’t love.” But what if that’s when love is actually starting to form—when your nervous system stops mistaking anxiety for passion?
A Personal Reckoning
I remember once being convinced I’d found “the one”. Every conversation felt electric; every silence, poetic. I could barely work, eat, or think of anything else. But when the hormones retreated, reality arrived uninvited. We had different values, mismatched patience levels, and a shared inability to communicate once the thrill dimmed. What I thought was love was, in truth, my brain on dopamine.
Months later, I met someone whose presence didn’t set off fireworks—but it brought ease. My body didn’t tremble; it relaxed. That calm, I later realised, was the absence of hormonal chaos. It was the beginning of something steadier.
Psychology Meets Biology
From a psychological standpoint, love is an attachment bond built through emotional safety, mutual vulnerability, and shared experiences. Hormonal infatuation, meanwhile, is a neurochemical spike designed to spark interest, not sustain it.
Hormones ignite; psychology endures.
When you’re merely under hormonal influence, your focus is on how the person makes you feel—desired, thrilled, alive. When you’re in love, your attention turns outward: you care about their wellbeing, their growth, their fears. Lust says, “I want you.” Love says, “I want you to be well.”
One is need; the other is nurture.
The Emotional Compass Test
A small, unscientific test: notice your state when you’re apart. Hormones crave proximity and panic in separation. Love, though it misses, also trusts. Hormones ask for possession; love grants freedom.
If the connection survives the ordinary—the laundry, the disagreements, the unfiltered mornings—it’s likely more than hormones. Love isn’t just the high; it’s the habit of care that remains after the high has left.
Why It’s So Hard to Tell
Part of the confusion comes from our wiring. Evolution designed us to overestimate romantic potential—it kept our species going. So yes, biology will lie to you, convincingly. And yes, psychology will take its time revealing the truth.
That’s why the early months of love are both thrilling and unreliable. You can’t fully know someone—or your own mind—while intoxicated by chemical infatuation. The real test of love is time, not intensity.
Hormones fade; patterns don’t. Observe how both of you handle boredom, conflict, and imperfection. That’s where truth hides.
A Society That Mistakes Chemistry for Destiny
We glorify “love at first sight”, but rarely discuss the quieter truth of love at tenth argument. The media trains us to chase chemistry, not compatibility. The result? A world full of people mistaking adrenaline for alignment.
We swipe for instant sparks, ghost when the high fades, and call it “falling out of love”. Maybe we’re not falling out—maybe we’re finally sober. It’s not that love has died; it’s that hormones have stopped lying.
So, How Do You Know?
You know you’re in love when the person’s imperfections don’t scare you off. When the relationship feels less like a roller coaster and more like a rhythm. When peace feels more exciting than chaos.
You know it’s hormones when the thrill fades and there’s nothing left but silence and unmet expectations. When what once felt magnetic now feels empty because the chemistry had no foundation beneath it.
Love is a steady flame. Hormones are fireworks. Both light up the sky, but only one can keep you warm.
And perhaps, that’s the quiet miracle of it all—we start with biology, but if we’re lucky, we end in something that transcends it.
