An "affair" typically refers to a romantic relationship between two people, often when one or both are already in committed relationships. These relationships can be emotional or physical and usually involve secrecy. Affairs can lead to significant consequences, including heartbreak, trust issues, and the potential end of marriages or partnerships. People engage in affairs for various reasons, such as feeling unfulfilled in their current relationship or seeking excitement. The impact of an affair can ripple through families and friendships, affecting not just the individuals involved but also their loved ones, like spouses and children.
