You're lying awake at 2:00 AM. Your phone is glowing on the nightstand, and you're staring at a ceiling fan that needs cleaning, wondering about that person. You’ve been seeing them for three weeks, maybe three months, and the internal monologue is loud. How will I know if this is actually the real thing or just my brain dumping a bucket of dopamine on my common sense?
It’s a terrifying question. Honestly, it’s probably the most human question we ever ask. We’ve all seen the movies where there’s a sudden lightning bolt or a chorus of angels, but real life is messier. It's quieter. Sometimes it’s even a little bit boring, which is a weird thought, right? Most people expect fireworks, but the experts—the psychologists who actually study attachment theory and neurological mapping—say that the "fireworks" might actually be a red flag for anxiety rather than a green light for soulmates.
The Biology of the "Click"
We have to talk about the brain first because your gray matter is basically a drug lab. When you’re in those early stages, your ventral tegmental area (VTA) is working overtime. This is the part of the brain associated with reward and motivation. According to Dr. Helen Fisher, a biological anthropologist who has spent decades putting people in fMRI machines to study love, being "in love" looks remarkably similar to a cocaine addiction on a brain scan.
So, how will I know the difference between a chemical high and a lasting connection?
The high is frantic. It’s obsessive. It’s that feeling where you can’t eat, you can’t sleep, and you’re constantly checking your notifications like a lab rat hitting a lever for a sugar pellet. But lasting love—the kind that builds a life—usually shows up as a sense of "pre-attentive safety." It’s a physiological calm. Your heart rate actually tends to regulate when you’re near them. If you feel like you’re constantly on edge or "performing" to keep them interested, your nervous system is telling you something important. Listen to it.
The Boredom Test
This sounds counterintuitive. We’re taught that love is a high-speed chase. But one of the most consistent indicators of a healthy, long-term match is how you feel when absolutely nothing is happening.

Think about a rainy Tuesday. No fancy dinner. No vacation photos for Instagram. Just you, them, and a pile of laundry. If that scenario doesn't make you want to jump out of a window, you're on the right track. Dr. John Gottman, the famous relationship researcher who can predict divorce with over 90% accuracy, talks about "bids for connection." These are small, boring things. You point at a bird outside. They look. That’s it. That’s the "how will I know" moment. It’s the consistent response to those tiny, mundane bids that builds the "Emotional Bank Account."
If they ignore your small observations or make you feel stupid for sharing them, the foundation is cracked. It doesn't matter how great the sex is or how much you both like the same indie bands. If they don't turn toward your bids, the relationship is statistically likely to fail.
Red Flags vs. Pink Flags
We talk a lot about red flags—abuse, gaslighting, total lack of empathy. Those are easy (well, easier) to spot once the fog clears. But what about the "pink flags"? These are the subtle things that answer the how will I know question over time.
- Do you feel like you’re shrinking yourself to fit into their life?
- Do you find yourself "translating" their bad behavior to your friends? "Oh, they didn't mean it that way, they're just stressed."
- Are you more in love with their potential than who they actually are right now?
The "Potential Trap" is a killer. You see someone’s trauma and think you can heal it, or you see their talent and think you can motivate them. But you’re dating a human being, not a DIY home renovation project. If you have to change 40% of their personality for them to be "the one," they aren't the one.
Attachment Styles and the "Spark"
A lot of people think the "spark" is chemistry. Sometimes, it’s just your attachment styles clashing in a way that feels familiar. If you have an anxious attachment style, you might be drawn to avoidant people. That "pull" you feel? That's not love. That's your anxiety being triggered because they are being distant. It feels intense, so we label it as passion.

In reality, secure love feels... well, secure. It’s a bit predictable. And for people used to chaos, "predictable" can feel like "boring." You have to retrain your brain to realize that peace is actually the goal. You’ll know it’s working when you don't feel the need to "game" the relationship. You don't have to wait three hours to text back because you aren't afraid of looking "too interested." You just are interested. And they are, too.
Conflict is Actually a Good Sign
Wait, what?
Yes. If you never fight, you’re probably not being honest. Total harmony is often a sign of "conflict avoidance," where one or both people are burying their needs to keep the peace.
The real answer to "how will I know" lies in how you fight. Do you attack the problem, or do you attack each other? If you can disagree about the dishes or the budget without someone feeling belittled or shut down, that’s a massive indicator of longevity. Healthy couples use "I" statements. They don't use "always" or "never." They don't use "The Four Horsemen" (Gottman’s terms): Criticism, Contempt, Defensiveness, and Stonewalling. Contempt—eye-rolling, sneering, acting superior—is the single biggest predictor of a breakup. If it's there, pay attention.
Values vs. Hobbies
You both like hiking? Great. You both love 90s hip-hop? Cool. None of that matters for a long-term partnership.

Hobbies change. Bodies change. Interests fade. Values are the bedrock. To know if it's real, you have to look at the big stuff:
- Money: How do they view debt? Are they savers or spenders?
- Family: Do they want kids? How do they treat their parents? How do they want you to treat their parents?
- Growth: If you want to go back to school or change careers in five years, will they be your cheerleader or an anchor?
If your values are aligned, you can survive the "boredom" and the "drifts" that happen in every long-term relationship. If they aren't, the hobbies won't save you.
Actionable Steps for the "How Will I Know" Phase
If you're currently in the middle of this internal debate, stop thinking about "forever" for a second. It's too big. Instead, try these three things to get some clarity:
The 24-Hour Silence Test
Spend 24 hours alone. No texting them, no checking their social media. How do you feel? If you feel a sense of relief or a return to yourself, you might be losing your identity in the relationship. If you feel a quiet, steady warmth—rather than a panicked need to reach out—that’s a healthy sign of secure connection.
The "Worst Version" Visualization
Imagine your partner is having a terrible week. They’re sick, they’re cranky, they haven't showered, and they’re being kind of annoying. Do you still want to be in the room with them? If you only love them when they’re "on" and being their best self, you’re in love with an image, not a person.
The Values Audit
Write down your top three non-negotiable life values. Not "funny" or "hot." Think "financial transparency," "emotional honesty," or "independence." Does your partner actually live these values, or do they just talk about them? Watch their actions, especially when they think you aren't looking.
Realizing "how will I know" isn't a single moment. It’s a collection of data points. It’s the realization that you don’t have to "find" the right person as much as you have to "build" a right relationship with someone who is willing to put in the work. It’s less like a lottery win and more like growing a garden. It takes time, it’s occasionally back-breaking, but when it blooms, you don't have to ask the question anymore. You just know.
