A love triangle is a scenario or circumstance, usually depicted as a rivalry, in which two people are pursuing or involved in a romantic relationship with one person, or in which one person in a romantic relationship with someone is simultaneously pursuing or involved in a romantic relationship with someone else. A love triangle typically is not conceived of as a situation in which one person loves a second person, who loves a third person, who loves the first person, or variations thereof.
Love triangles are a common narrative device in theater, literature, and film. Statistics suggest that, in Western society, "Willingly or not, most adults have been involved in a love triangle."
