Love is a complex emotion that can be difficult to define, but it generally encompasses a range of strong and positive emotional and mental states. Love acts as a major facilitator of interpersonal relationships and is one of the most common themes in the creative arts. Love can be characterized by intimacy, passion, and commitment, and it involves care, closeness, protectiveness, and respect. Love can be experienced in various forms, including personal love, romantic love, and self-love. Ideas about love have changed greatly over time and across cultures. Love is an emotion that keeps people bonded and committed to one another, and it evolved to keep the parents of children together long enough for them to survive and reach sexual maturity. Love is defined differently from person to person, but it is generally an intense feeling of deep affection.
