Ambivalence is a state of having simultaneous, conflicting feelings toward a person or thing. Stated another way, ambivalence is the experience of having thoughts and/or emotions of both positive and negative valence toward someone or something. A common example of ambivalence is the feeling of both love and hate for a person. The term also refers to situations where "mixed feelings" of a more general sort are experienced, or where a person experiences uncertainty or indecisiveness concerning something. The expressions "cold feet" and "sitting on the fence" are often used to describe the feeling of ambivalence.
