In general, humans fall in love as an evolutionary response to ensure the continuation of the species. Humans are social creatures, and we form emotional attachments for support, a sense of belonging, and the biological drive to care for and protect loved ones.

No matter who you are or what your age, race, religion, or sexual orientation may be, it is a human phenomenon to love and be loved. In fact, the need for love is considered to be one of our most basic needs. According to psychoanalysts like John Bowlby and Abraham Maslow, being loved is as essential as food, water, and shelter.

In other cases, the explanatory reason for why we fall in love may be a complex assembly of factors, such as reciprocal liking, mystery and unpredictability, relationship readiness, and similar core values, attitudes, and personality traits.
