I fell in love with a pair of feet
I need to tell you a story that makes no sense — which is exactly the point.
A story about chemistry that defies all logic.
I popped around to a mate’s house one afternoon — nothing planned, just dropping in. I walked into the lounge and his sister had a friend visiting from Dorset, about two hours away. She was sitting on the sofa with her feet up.
I saw her feet first. And I fell in love. Instantly. Before I’d even looked up.
I’m aware of how that sounds. And I should be honest: she had rather long toes. These were not objectively, conventionally, magazine-cover feet. But something in my brain — something I had absolutely no control over — fired a signal so powerful that by the time I looked up and saw her face, the feeling didn’t start. It compounded. It was already there. Her face just confirmed what my nervous system had apparently already decided.
We ended up together for five years.
To this day, I cannot explain what happened in that moment. No amount of psychology textbooks has given me a satisfying answer for why a pair of slightly unusual feet triggered the most immediate, overwhelming sense of recognition I’ve ever felt. It wasn’t sexual. It wasn’t rational. It was something else entirely — something that arrived before thought, before assessment, before any of the machinery of attraction had time to engage.
That’s chemistry. Real, undeniable, inexplicable chemistry. And it led to five genuinely wonderful years — so I’m not going to stand here and tell you it was wrong. It wasn’t. That lightning bolt led me to someone who changed my life.
But here’s the nuance I want to explore: the feeling was real, and it happened to work out — but the feeling alone didn’t tell me it would work out. I got lucky. The chemistry pointed me at someone who was actually compatible. It doesn’t always. And when it doesn’t, the intensity of the feeling can keep you locked into something that’s hurting you, because you mistake the fireworks for proof.
So this isn’t an article about chemistry being fake. It’s about learning to read it — to tell the difference between a signal worth following and your nervous system misfiring.
Everyone’s chasing the spark
Think about the last time you had an incredible first date. The kind where the hours vanished, your heart was racing, you couldn’t stop thinking about them afterwards. You probably described it as “amazing chemistry.”
Now think about the last time you had a nice, pleasant, perfectly fine first date. Good conversation, genuine laughs, nothing wrong with it at all. And you probably said something like: “They were lovely, but… there was no spark.”
Here’s the uncomfortable question: what if the first person made you feel that way because they triggered your anxiety — and the second person felt “boring” because they made you feel safe?
What’s actually happening in your brain
When you feel “chemistry” with someone, your brain is running a very specific neurochemical programme:
Dopamine surges — the neurotransmitter of novelty and reward. Dopamine doesn’t respond to satisfaction; it responds to anticipation. Uncertainty (“do they like me?”) is one of the most powerful dopamine triggers that exists.
Norepinephrine floods your system — heart racing, palms sweating, can’t eat, can’t sleep. This is your body’s arousal system in overdrive.
Serotonin drops — which is associated with the obsessive, intrusive thinking patterns. “Why haven’t they texted back?” That loop is a serotonin deficit.
Now here’s the thing: this neurochemical cocktail is almost identical to anxiety. Literally the same molecules, the same brain regions, the same physical sensations. Racing heart, heightened alertness, obsessive thinking, butterflies in your stomach — these are symptoms of both falling in love and having a panic attack.
Your brain cannot reliably tell the difference. And that’s where the trouble starts.
The anxious-avoidant trap
Attachment theory — developed by John Bowlby and applied to adult relationships by Hazan and Shaver — divides people into roughly four attachment styles: secure, anxious, avoidant, and disorganised (a combination of anxious and avoidant).
Here’s the pattern that plays out millions of times, on millions of dates, every single week:
An anxiously attached person meets an avoidant person. The avoidant person sends mixed signals — warm one day, distant the next. This creates massive uncertainty. Uncertainty triggers dopamine. Dopamine feels like chemistry. The anxious person thinks: “I’ve never felt this way about anyone before. This must be love.”
It’s not love. It’s their attachment system in overdrive.
Meanwhile, when an anxiously attached person meets a securely attached person, the secure person is consistent, available, and straightforward. No mixed signals. No uncertainty. No dopamine rollercoaster. And the anxious person thinks: “They’re nice, but there’s no spark.”
The devastating finding: what most people call “chemistry” correlates more strongly with attachment insecurity than with actual compatibility.
The most intense initial “chemistry” tends to occur in the pairings most likely to fail long-term. The calmest initial connections tend to occur in the pairings most likely to succeed.
A question worth sitting with.
That relationship I started through an inexplicable pair of feet? It was wonderful — genuinely one of the most important relationships of my life. The chemistry got us through the door, and what we built together kept us there for five years. But was the lightning bolt the reason it worked — or just the reason it started? Would I have walked past someone equally compatible if the initial feeling hadn’t been so dramatic?
Think about your own experience. The relationships that gave you the most intense initial feelings — the dizzying highs and devastating lows. And then think about the people in your life where you feel most consistently safe, valued, and yourself.
Are they the same people?
For most of us, they’re not. And that gap is worth understanding.
So should you ignore chemistry entirely?
No. Absolutely not. Chemistry matters — but you need to learn to read it.
Good chemistry looks like:
- Energy and ease — you feel more alive, not more anxious
- Curiosity — you want to know more about them, not just whether they like you
- Comfort with silence — pauses feel natural, not terrifying
- Mutual disclosure — both of you are opening up, not just one
- You leave feeling good — not obsessive, not drained, just… good
False chemistry looks like:
- Obsessive thinking — can’t stop analysing every message
- Walking on eggshells — monitoring your behaviour to keep their approval
- Extreme highs and lows — euphoria one day, despair the next
- Relief, not joy — when they text back, you feel relief rather than happiness
- You leave feeling unsettled — something’s off but you can’t name it
The “calm chemistry” of secure attachment
Secure attachment doesn’t feel boring — it feels different. It’s the warmth of being genuinely seen. The ease of not having to perform. The quiet confidence that this person isn’t going anywhere.
It’s less like a fireworks show and more like a fire you actually want to sit beside.
How to test real compatibility beneath the surface
This is exactly why guided conversation tools exist. When you’re running purely on “chemistry,” your brain is in dopamine mode — it’s not doing careful compatibility assessment. It’s chasing the high.
Dive Deep Dating’s questions are designed to cut beneath the surface. They’re fun enough to feel like a great date, but structured enough to reveal who someone actually is — their values, their conflict style, their capacity for vulnerability.
Deep Dive takes it further for couples getting serious — four levels of carefully-researched questions about the things that actually predict long-term success: financial values, family expectations, how they handle disagreement.
Neither replaces chemistry. But both give you data that chemistry alone doesn’t.
A reframe that might change your dating life
Instead of asking yourself “Do I feel a spark?” after a date, try asking:
“Did I feel safe enough to be honest?”
That’s a much better predictor of long-term compatibility. The spark fades — every bit of neuroscience confirms this. What remains is whether two people can be real with each other.
If you felt safe being honest with someone on a first date, that’s not boring. That’s rare. That’s worth a second date.
