This research is motivated by the phenomenon of obsessive love in romantic relationships, which is often represented in films as an unhealthy relationship characterized by emotional dependency, possessive behavior, excessive control, and destructive actions. The film Cinta Mati portrays the transformation of a romantic relationship from affection into manipulative and violent behavior due to the psychological conflicts experienced by the main character. This study aims to describe the forms of obsessive love, the personality structure based on Sigmund Freud’s psychoanalytic theory, and the psychological dynamics of obsessive love experienced by the main character in the film Cinta Mati. This research employs a descriptive qualitative approach, with data sources consisting of dialogues, monologues, and film scenes. The data were analyzed using the interactive model of Miles, Huberman, and Saldaña through the stages of data condensation, data display, and conclusion drawing. The results of the study reveal 27 data findings related to forms of obsessive love, 30 data findings related to personality structures consisting of the id, ego, and superego, and 25 data findings related to the psychological dynamics of obsessive love. The uniqueness of this research lies in its analysis of the development of obsessive love, which not only examines the character’s external behavior but also reveals internal conflicts through the interaction of the id, ego, and superego from Freud’s perspective. The findings indicate that obsessive love develops gradually from emotional dependency, fear of loss, and jealousy into manipulation, violence, and destructive behavior. This research contributes to the field of literary psychology by expanding the understanding of the relationship between psychological conflicts and human behavior, while also serving as a reflection for society in recognizing signs of unhealthy relationships.
