Love vs Infatuation: How to Tell the Difference
Entry No. 158 ·
By The IF Team
Infatuation is an intense, fast-building attraction that runs mostly on passion and imagination: you are captivated by someone, often before you really know them, and much of what you adore is the version of them in your head. Love includes passion too, but it adds knowledge and choice. You know the person, irritating parts included, and you want good things for them on dull days as well as bright ones. Lust is physical desire, and it can come with either, or with neither. In the first weeks you often cannot tell which you are feeling, and that is normal: time, ordinary days and a few small disappointments are what reveal the difference.
Being infatuated is not shallow, and it is not a mistake. Most love stories start exactly here: the racing thoughts, the reread messages, the conviction that this person is different. The question is not whether the feeling is legitimate. It is what the feeling is made of, and what it might become.
That question is easier to live with when nobody forces you to act on it at once, which is the idea IF was built around. On IF you can tell someone what you feel in honest words, whether you are single or taken and whoever has captured you, then act on it once the time is right. That leaves room to discover whether a feeling is infatuation, love, or the first becoming the second.
If yours is the all-consuming, cannot-eat, cannot-sleep kind, read what limerence is as well: it is a close cousin of infatuation, with patterns and a way out of its own.
Lust, infatuation and love run on different systems
The anthropologist Helen Fisher and her colleagues proposed that romance draws on three distinct but interrelated brain systems: lust, the craving for sexual contact; attraction, the focused, energised longing for one particular person; and attachment, the calm sense of security and union that keeps two people together. Infatuation sits squarely in the second. Love, in the long-lasting sense, needs the third as well.
Because the systems are separate, they do not always arrive together. You can feel a strong physical pull towards someone you have no wish to date, a dizzy fixation on someone you barely know, or a deep, unshowy attachment that never once made your heart race. None of these is wrong. Knowing which is which simply saves a great deal of confusion.
What Sternberg’s triangle says about infatuation
The psychologist Robert Sternberg described love as a triangle with three sides: passion, intimacy and commitment. In his model, passion on its own, without intimacy or commitment, is what he called infatuated love. Intimacy on its own is liking. Passion and intimacy together make romantic love, and when commitment joins them you reach what he called consummate love.
The triangle doubles as a practical test: ask which sides your feeling actually has. Passion you can feel from across a room. Intimacy takes conversations, confidences, and seeing someone tired or upset. Commitment is a decision, made and then kept. If all you can honestly vouch for is the first, you are probably infatuated, which is a perfectly good place to start.
Love vs infatuation: how they behave over time
Neither feeling announces itself, but over a few weeks they tend to act quite differently:
- Speed. Infatuation arrives fast, sometimes within an evening. Love usually builds, even when the first spark was instant.
- What you know. Infatuation fills the gaps in your knowledge with flattering guesses. Love is built from what you have actually learned, including things you did not expect.
- Where your mind wanders. Infatuation drifts to scenes — the first kiss, the holiday, the moment they finally say it. Love drifts to them: how their interview went, whether their cold is any better.
- How their flaws land. Infatuation edits them out, then feels betrayed when they appear. Love knows the list by heart and is fond of half of it.
- What you want for them. Infatuation wants them, mostly. Love wants good things for them, even things that take them away for a while: a job in another city, a weekend with their oldest friends.
- How it feels to be apart. Infatuation can make a day without them feel like withdrawal. Love misses them and gets on with the day.
If your infatuations tend to land on people who keep you guessing, your attachment style may be part of the reason.
Where lust fits
Lust is the simplest of the three, and the most misunderstood. It is physical desire, and it can be part of infatuation, part of love, or neither. A strong physical pull towards someone does not mean you love them, and the absence of an instant spark does not mean you never will: plenty of lasting couples describe an attraction that grew as they got to know each other.
Chemistry is real and good, but it is not the same as getting on well, and chemistry vs compatibility explains why the two are worth weighing separately.
How long does infatuation last?
There is no fixed timetable. When the psychologist Sandra Langeslag and her colleagues built a questionnaire to measure romantic love, infatuation and attachment came out as two separate components, each measurable on its own. Infatuation is usually at its fiercest early in a relationship, while attachment tends to deepen with time. In a relationship that lasts, the first gradually makes room for the second, though the happiest couples keep a little of both.
If you are in the giddy early stage of something new, how long the honeymoon phase lasts covers what happens as it settles.
Can infatuation turn into love?
Often, yes. Infatuation is one of the commonest ways love begins. What turns one into the other is not the intensity of the feeling but what gets added to it: real conversations, seeing each other at your worst as well as your best, being let down a little and staying, choosing each other on an ordinary Tuesday. If you are noticing those things, the signs you are falling in love will feel familiar.
Sometimes the opposite happens, and that is no failure either. As you get to know someone, infatuation can fade into friendship, indifference or a fond memory. Better to learn that over a few months than to build a life on a highlight reel.
Infatuated with someone you cannot be with
Infatuation thrives on distance, so it often fixes on people we cannot easily have: someone in a relationship, someone we only ever see across a room, someone whose timing never quite matches ours. With little to go on, imagination fills in the rest, and the feeling can run for months.
That does not make it fake, and it does not make you foolish. It does mean you do not yet know what you would feel up close. If they are in a relationship, your real options when your crush is taken is written for exactly this. And if you want to say how you feel without pushing anyone, an IF lets you put it into words now and leave it to the timing to show whether this was a passing infatuation or something that deserved to wait.
Where IF fits: time to find out what it is
IF exists for feelings that are real but cannot be acted on yet. Singles and people in relationships take what they feel for someone they know in real life, put it into an IF, and act on it when the time is right, whatever their status and whoever it is for.
Both single, and they have a profile? Then a Like is enough, and if they accept it, the two of you can start chatting. If one of you is in a relationship, or IF is new to them, you write an IF: 250 characters at most, kept sealed. You can come across them on Swipe, or key the email, mobile number or Instagram handle they gave you into Search. An email address receives a single short invitation. A phone number or a handle receives nothing, and your IF quietly bides its time in case they join.
While one of you has a partner, there is no chat to open on IF at all, so an IF to someone taken stays exactly what it is — a feeling, written down — until you are both single. Someone on IF may see a notice that an IF has arrived for them; until it is revealed, that notice keeps both your name and your words to itself, though a good guess is always possible.
For infatuation, that is the kindest possible test. If the feeling fades, your IF has asked nothing of anyone in the meantime. If it lasts, it is already said. And the first IF you send is free.
Questions people ask
Is infatuation a bad thing?
No. It is a normal, often wonderful feeling, and many relationships begin with it. It only causes trouble when it is mistaken for knowledge, and big decisions get made on the strength of someone you have mostly imagined.
What is the difference between love and lust?
Lust is physical desire. Love is a wider bond that includes caring about someone’s wellbeing, knowing them well and choosing them over time. Lust can be part of love, but it can also exist entirely without it.
Can you be infatuated with someone you have just met?
Yes, and quickly. Infatuation needs very little information, which is part of its charm. Treat it as an invitation to get to know them, not as proof of anything yet.
Can infatuation last for years?
It can, especially when it has little contact with reality: a one-sided crush, someone far away, someone you rarely see. Up close, infatuation usually either deepens into love or fades within months. When it lingers for years at a distance, it is often living on the not-knowing itself.
You do not have to know yet whether it is love. Say it honestly, in person or in an IF, and let time tell you what it was.
