In this paper, we will explore the concept of love addiction, examining its manifestations and the aspects that differentiate the phenomenon from conventional falling in love. Attachment theory is an attractive model for understanding love addiction, which can highlight the impact of emotional bonds developed during childhood on adult relationships. We will, therefore, delve deeper into how the anxious-ambivalent attachment style, which in adulthood takes on the name of the insecure, worried attachment or insecure enmeshed attachment, seems to influence the propensity to love addiction. Understanding attachment theory provides a theoretical framework in which to think about the dynamics of love suffering, thus providing the conditions to increase awareness of the phenomenon's origins and contribute to the promotion of more satisfying relationships
