There’s a specific kind of man I need to tell you about.
He’s not the obvious one. He’s not mean or dismissive or clearly unavailable. He doesn’t show up late consistently or forget your birthday or disappear for days without explanation. He’s not the kind of guy your friends would look at and say yeah, we saw that coming.
He’s the one they liked. The one you liked. The one who made you feel, for the first time in a long time, like maybe this was actually it.
He was intense. Present. When you talked, he listened — not the half-listening that most people do, but the kind where he remembered things and asked follow-up questions and made you feel like the most interesting person in the room.
There was electricity. Real electricity. The kind where you’d be in the middle of a completely normal Tuesday and think about something he said and feel it in your chest.
And then slowly — not all at once, but slowly — things started to feel unstable. A little anxious. Like you were always slightly off-balance, always not quite sure where you stood, always waiting for the other shoe to drop even on the good days.
And here’s the thing that took me the longest to understand: that instability was not separate from the chemistry. It was the source of it.
The thing I had been calling chemistry was, at least in part, anxiety. A nervous system on high alert. A brain flooded with stress hormones doing a very convincing impression of excitement.
This is the red flag that almost no one talks about in the early stages — because it doesn’t feel like a red flag. It feels like falling in love.
Let me explain exactly what it is, how it works, and how to tell the difference between the real thing and the very persuasive imitation.
The science part — stay with me, it matters
In 1974, two psychologists named Dutton and Aron ran a study on a suspension bridge in British Columbia. They had an attractive woman approach men either on a scary, swaying bridge high above a gorge, or on a solid, low bridge nearby. She gave them her number. The men on the scary bridge were significantly more likely to call.
The interpretation: their bodies were already activated — heart pounding, adrenaline elevated, senses heightened — and when the woman appeared, their brains attributed some of that arousal to attraction. The fear and the desire got mixed up. Mislabeled. The brain experienced activation and called it chemistry.
This isn’t a niche psychological curiosity. It’s a fundamental feature of how we work. Our bodies generate a physiological state. Our minds assign meaning to it afterward. And they don’t always get it right.
Now bring that into the context of an early relationship with someone who is — whether consciously or not — creating unpredictability. Hot and then a little cold. Intensely present and then briefly distant. Deeply affirming and then mildly withholding. Nothing dramatic. Just enough variation that your nervous system never fully settles.
Your heart rate is up. Your attention is narrowed. You’re checking your phone a little more than you’d like. You’re replaying conversations. You’re alert, activated, alive in a way that quiet, stable relationships don’t always produce.
And your brain looks at all of that activation and says: this must be love.
What it actually looks like in a person
Here’s where I want to get specific, because this is the part that matters.
The man who generates this feeling is almost never doing it with a sign on his chest. He’s usually doing it through very small, almost imperceptible patterns. The kind of things that individually sound like nothing — but together create a particular kind of relational weather.
He runs warm and cool in an inconsistent rhythm. Not dramatic hot-and-cold. Just slightly uneven. Three days of deep connection, then one day where he’s a little flat and you can’t quite tell why. A week of consistent texting, then a gap that feels different from the previous ones and you’re not sure why it feels different, just that it does. The inconsistency is subtle enough that you can’t point to it clearly. But your nervous system has mapped it perfectly.
He gives you just enough, just often enough. His attention, when it comes, is extraordinary. His affection, when it shows up, is exactly what you wanted. The problem isn’t that he’s withholding — it’s that the good thing comes in irregular intervals. And irregular reward schedules are, as any behavioral psychologist will tell you, the most addictive kind. Slot machines work on irregular reward schedules. So does this.
There is always a very small amount of uncertainty about where you stand. Not enough to make you leave. Not enough to name clearly in a conversation. Just enough to make “I wonder if he…” the background music of your relationship. You’re never quite at rest with it. Never quite sure. And the moments when you feel sure — when he’s warm and direct and you feel it — those moments feel disproportionately good because of the contrast with the uncertainty.
Conversations about the relationship feel slightly slippery. You try to talk about something you noticed and somehow, by the end of the conversation, you’re discussing his needs instead of yours. Or you’re reassuring him when you came in needing reassurance. Or the conversation ends and you feel like you said everything wrong, even though you prepared. Not every time. Just often enough.
He is magnetic in groups. Confident, funny, at ease with people. And when he turns that attention fully toward you in a room full of people, it feels like being lit up from inside. Which means you always want to be in that spotlight. Which means you’re always, subtly, trying to earn it.
Why your body mistakes this for chemistry
Real chemistry does involve activation. That’s not wrong. New love is supposed to be electric.
But there are two very different kinds of activation at work in early romance, and they feel almost identical from the inside.
The first is approach activation — the warm, pulled-toward feeling of genuine desire and connection. Your body moving toward something that is actually good. Nervous system lit up in the way of excitement, possibility, joy.
The second is threat activation — the stress response your nervous system generates when something is slightly off, slightly unpredictable, slightly unsafe. Heart rate up. Attention narrowed. Hypervigilance dressed up as intensity.
Here is the brutal part: if you grew up in an environment where love was inconsistent, conditional, or required your performance — threat activation may feel more like home than approach activation does. Not because you’re broken. Because you’re familiar. Your nervous system learned, very early, that this particular kind of tension means someone important is here. It learned to associate love with alertness.
So when you meet someone who is predominantly warm and stable and uncomplicated, it can feel flat. Pleasant but flat. Like something is missing.
And when you meet someone whose love comes in irregular intervals, whose warmth has to be earned, whose attention is extraordinary but not quite consistent — your nervous system lights up and calls it chemistry. Because it recognizes this. Because this is the feeling it learned to call love.
I want to say this as plainly as I can: that recognition is not evidence that he is right for you. It is evidence of what you were taught to want.
The difference between chemistry and anxiety: a checklist you can actually use
This is the part I want you to save. Come back to it. Read it on a day when you’re trying to figure out if what you’re feeling is real.
It might be anxiety disguised as chemistry if:
- You feel more relief when he texts back than excitement that he texted
- You think about the relationship most when something felt off, not when things are good
- The best moments feel electric partly because of contrast with the uncertain ones
- You spend more energy managing his mood than enjoying his company
- You feel like you’re always slightly auditioning, even months in
- “He makes me feel alive” is inseparable from “I never quite know where I stand”
- After spending time with him, you often feel unsettled rather than settled
- You feel the need to look back through old texts to reassure yourself he does love you
- His approval makes you feel great. His neutral mood makes you feel like you did something wrong.
- You are performing some version of yourself — the cooler, lower-maintenance, more agreeable version — and it takes effort to maintain
It’s more likely real chemistry if:
- You feel genuinely happy and calm after being with him — not just relieved
- You can be in a weird mood around him and it doesn’t threaten anything
- When he’s quiet, you assume he’s just quiet — not that something is wrong
- You feel free to want things and ask for them without calculating the risk
- You bring more of yourself into this relationship over time, not less
- His consistency feels like a given, not a gift you’re afraid to lose
- You feel chosen in this relationship — not lucky
The hardest part of all of this
I need to say something that is difficult to sit with.
If the first checklist describes your current relationship — if you read those bullet points and felt that faint sick recognition — it doesn’t automatically mean you should leave. Relationships are complicated. People are works in progress. Some of what looks like inconsistency in early relationships is genuinely just two people finding their footing.
But it does mean something worth taking seriously: your nervous system is telling you it is not at rest. And a nervous system that is not at rest cannot see clearly. You will interpret everything through the lens of the anxiety. Good things will feel temporary. Small problems will feel like proof of your worst fears. You will work very hard, in very quiet ways, to stabilize something that may not be stable by nature.
And here’s the other hard thing: sometimes, when you find someone who is genuinely stable and consistent and warm without the variable schedule — it initially feels boring. Flat. Like the chemistry isn’t there.
I want to ask you to stay with that feeling long enough to question it. Not to talk yourself into someone you’re not attracted to. But to ask whether what you’re calling “no chemistry” might actually be “no anxiety.” Whether what you’re calling “flat” might actually be “safe.”
Because safe is supposed to feel like something. It’s supposed to feel like coming in from the cold. Like exhaling. Like oh — this is what they meant.
It doesn’t always feel like electricity. But electricity, in the wrong wiring, burns things down.
What to do with this
If you’re in something right now and the first checklist felt uncomfortably familiar, here’s what I’d suggest — not as a therapist, just as someone who spent a lot of time on the wrong side of this distinction.
Name what you’re actually feeling. Not the story you’re telling about it — the actual physical feeling. Is it warmth and expansion? Or is it tension, alertness, a faint underlying current of anxiety that you’ve been calling excitement?
Notice what happens after. After you spend time together, after a text exchange, after a good night — do you feel more settled or less? Do you feel more yourself or less? The aftertaste of your time together tells you more than the taste does.
Ask yourself what you’d feel if he suddenly became consistently warm, transparent, and available. Relief? Joy? Or — and this is worth sitting with — would some part of you feel the electricity go out? Would you worry you’d lose interest?
That answer is information. Not a verdict. But important information.
And if you’ve ever come out the other side of one of these relationships — the kind that felt like electricity and turned out to be anxiety — and found your way to something quieter and more solid: you already know everything I’m trying to say.
You know that the real thing doesn’t make you check your phone every twenty minutes.
It makes you put it down.
