Biological laws state that romantic feeling is a fleeting chemical process, lasting three years. Our physical attraction to the object of passion is associated with increased testosterone and estrogen; falling in love is associated with dopamine, noradrenaline, and serotonin.

But love is not only physical passion, it is also communication between partners. A relationship becomes a comfort zone for a person. When the level of trust between partners is high enough, a relationship filled with love can last much longer than three years.

Symptoms of love are similar to a painful state: sweaty palms, loss of appetite, euphoria, a blush on the face, and a rapid heartbeat. Love goes through several stages - each of them depends on certain chemical elements triggering the corresponding reactions in the body.

Falling in love is fleeting, love is lasting.
Infatuation does not live long - it is not able to develop and adapt. Love, on the other hand, is resilient, flexible and adaptable to change. True love will survive all the storms of life.
Perhaps there is a proven concept that love lives for 3 years.
But each person is unique in its own way and is able to understand as he wants and actions that will lead to completely different results. There is no one-size-fits-all solution to this issue, because every relationship is unique. But there are steps that partners can always take.
