A concept of social and emotional psychology that describes how attractive qualities of a partner or romantic relationship can become sources of conflict and frustration in the long run. The term has been widely coined by relationship researchers, in particular Leslie Watson and her colleagues (LW Waller & L. Watson, 1994), to explain a common phenomenon in romantic relationships where what initially attracted a person later becomes the primary reason for the end of a relationship. A socio-psychological concept that describes how characteristics that initially attracted a person to a partner, such as optimism, courage, independence, or vitality, can later become problematic or cause problems as the relationship continues, causing conflict, resentment, and sometimes separation. The fatal attraction model suggests that attractive qualities that initially unite people can later become sources of tension or separation. Understanding this model helps to predict potential areas of conflict, improve communication, and manage relationship expectations more realistically.
