“Falling in love is like being on a mind-altering drug literally.” Not a cheesy metaphor, but a scientific fact. When the butterflies alight, your brain is filled with chemicals that can get even the sanest human being slightly wild, slightly crazy, and very much like the heroine of a romantic comedy. But what when the high wears off? Love, or the glow of infatuation?
It takes one of the most difficult and most essential skills in a relationship to be able to distinguish between loving someone and being in love. Anyone can fall under the high of the beginning, but creating an enduring relationship involves more than fantasies driven by dopamine. These are the methods science, psychology, and real experiences can help you crack what you’re truly feeling and why it’s good for your heart (and your well-being).

1. The Dopamine High Vs. the Oxytocin Calm
The early stages of romance can feel like a caffeine overdose racing heart, sweaty palms, and an all-consuming focus on your new flame. This isn’t just your imagination. As Dr. Helen Fisher’s research at Harvard Medical School revealed, the brain’s reward circuit lights up with dopamine when you’re falling in love, making the experience feel as addictive as a drug. The ventral tegmental area, responsible for pleasure and motivation, is hyperactive, and serotonin decreases, causing those obsessive thoughts (romantic love induces the dopaminergic peaks and the decrease in serotonin).

But then the grown-up version comes in: oxytocin, or the “bonding hormone.” This shift provides you with a feeling of calmness, safety, and profound attachment. With oxytocin pumping through your veins, you leave the thrill ride of infatuation and into the flatline tranquillity of profound attachment (oxytocin makes emotional connection meaningful). That’s why long-term couples will say they talk about their love as a sanctuary, not a rollercoaster.

2. Idealisation and Obsession vs. Acceptance and Realism
In love, your beloved is magical to you yes, even their taste in music. Your brain reward system reinforces this idealisation by closing down the neural pathways associated with critical judgment. As Harvard Medical School’s Dr. Schwartz explains, “That’s the neural basis for the ancient wisdom ‘love is blind’.(love shuts down judgment pathways)
Eventually, however, rose-colored glasses fall off. Real love is accepting your partner’s flaws and quirks and loving him despite it.” Therapist Linda Carroll, in an article for Psychology Today, comments, “Growing to love the real person and accepting who they are, with both strengths and weaknesses, can make a wonderful difference in your relationship, helping it to become a lasting source of comfort, emotional safety, and a wonderfully sustainable joy” (accepting reality deepens love). That turn from fantasy to acceptance requires some maturity, long-term relationship.

3. Passion and Urgency and Stability and Partnership
The honeymoon phase is all about possession, desperation, and fixation to be with your person 24/7, to the extent of losing yourself at times. It is high-energy expected but not a good place to be for very long. “Being in love is a temporary phase at the beginning of a relationship. There is the excitement and newness of the love interest and the unknown.” (being in love is temporary)

Over time, interest turns into partnership and support. Impressing or trying to impress is no longer a concern as equality and co-operative partnership are formed. “Having a sense of ownership of the person is largely thought of as taking place during the infatuation or in-love stage.” The ownership stage is parading the one loved around like they are a trophy. The second type of thinking in the relationship, equaling better describes the love,” Choosing Therapy (partnership speaks mature love) continues to say. Stability, not sexy, is what leads to long-term relationships.

4. Evading Conflict vs. Riding the Highs and Lows of Life
Early love is the type of love that is full of boat-rocking fear. Couples do not wish to struggle hard to maintain the magic but this brings problems and emotional distance that will haunt them in the long run. When the infatuation dies off, fights may be too much, even cataclysmic to the relationship’s future (fights feel too much in early love).

Alternatively, adult love welcomes conflict as a way of deeper comprehension. Love-struck couples are willing to have tough conversations knowing that the relationship is strong enough to withstand the tempests. When you’re in the love relationship, you learn there are going to be those days that life with your partner isn’t so much fun, that your partner isn’t so much less than perfect as is perfect, and you can love and take her or him in bad times as in good times,” says Linda Carroll (accepting imperfection builds resilience). It’s this resilience that enables love to flourish in the presence of life’s inevitable ups and downs.

5. The Triangular Theory of Consummate Love: Sternberg
For the ultimate and long-term romance, try three-component psychologist Robert Sternberg’s Triangular Theory of Love. Sternberg thinks love is built on three legs: intimacy (affective closeness), passion (lust), and commitment (the choice to remain together). Combinations of these will generate various forms of love from the intensity of infatuation to the basis of companionate love (Sternberg’s theory charts the evolution of love).
The grand objective? Consummate love, in which the three elements are present. “Consummate love takes all three elements and is mature love. It is the perfect relationship. Couples who share this type of love have excellent sex a few years into the relationship. They can’t picture themselves in another relationship with someone else,” states Simply Psychology (consummate love is the best). Just because all relationships don’t turn into triple threats doesn’t mean learning about the ratios can’t give you a long-term love that’s just as fantastic later too.

Breaking up your feelings isn’t splitting between passion and partnership it’s being sensitive to the ways that love changes and what you really require. The high of being in love is exhilarating, but the safety of long-term love is where happiness truly grows. By learning the psychology and science behind your emotions, you can create relationships that are not only exhilarating but richly satisfying. The next time you get butterflies, you might ask yourself: is this a high, or the beginning of something wonderful? The answer could change your love life.
