Being controlling generally refers to a behavior or personality trait where an individual attempts to dictate or influence the actions, behaviors, or decisions of others to suit their own desires or expectations. A controlling person may use various tactics, such as manipulation, coercion, intimidation, or emotional abuse, to gain power or control over others. They may also have difficulty accepting alternative viewpoints or delegating tasks to others. This behavior can be harmful to relationships, as it can create feelings of resentment, anxiety, and mistrust in the people around them.
