The phrase that love lasts three years has long become part of popular culture. Many perceive it almost as an inevitable scenario: first, butterflies in the stomach, sleepless nights, and the desire to be together all the time, and then — utility bills, shopping lists, and arguments about who will take out the trash today. However, scientists believe that reality is much more complex and interesting.
Yes, the most intense romantic experiences cannot last forever. But this does not mean that relationships are doomed to fade after a few years. Psychologist Radmila Bakirova explained why feelings change and what helps maintain emotional closeness for many years.
The dopamine fireworks cannot last forever
At the beginning of a relationship, the brain is literally bathed in dopamine — the neurotransmitter of pleasure, motivation, and reward anticipation. It is what makes you constantly think about your loved one, check your phone every few minutes, and feel an emotional high.
"Research shows that the most intense stage of romantic love usually lasts from one to two years, although the timing can vary. The body simply cannot maintain such a level of neurochemical excitement constantly," the expert explains.
The main competitor of passion is routine
The problem is not that love disappears. The issue is that the human brain quickly gets used to even the most pleasant things.
When a relationship becomes completely predictable, the partner stops being perceived as a source of novelty. Meanwhile, novelty is one of the most important stimuli for the dopamine system. Therefore, many mistakenly interpret a decrease in emotional intensity as the disappearance of feelings.
New experiences help revive relationships
Interestingly, numerous studies show that couples who regularly gain new shared experiences usually feel happier and more satisfied with their relationships.
"This does not necessarily mean expensive trips. It can be a new walking route, a joint workshop, learning a foreign language, a new hobby, a trip to an unfamiliar place, or even an unusual photo shoot. For the brain, this is a signal that there is still something interesting and unexpected nearby," notes the psychologist.
It is important to rediscover each other
Many believe that after years of living together, they know their partner completely. In reality, people are constantly changing: new interests, dreams, fears, goals, and views on life emerge.
When partners stop asking each other questions and genuinely caring about each other's inner world, relationships gradually reduce to solving everyday tasks. Therefore, curiosity about the person often turns out to be just as important as romantic gestures.
Long-lasting love exists, but it looks different
After years, relationships rarely resemble the first months of acquaintance — and this is perfectly normal. Attachment, trust, a sense of security, and deep emotional closeness replace the hormonal surge.
The paradox is that the strongest couples usually do not try to endlessly maintain the state of first love. Instead, they create new shared memories, continue to be interested in each other, and allow their relationship to evolve alongside them.
Love does not really end after three years. It simply changes form over time. And if partners are willing to write new chapters of their story together, feelings can remain strong even after decades.
The initial bright emotions inevitably change, but this does not mean the end of love. Long and happy relationships are built not only on passion but also on trust, respect, shared experiences, and genuine interest in each other. It is the ability to grow together that helps preserve feelings for many years.
