This study reconstructed the participants' retrospective experience of how attachment avoidance and attachment anxiety developed during the course of romantic relationships in young adults. Participants (290 undergraduate students) recalled their stories of love relationships that occurred approximately between the ages of 15and19. The feelings of avoidance and anxiety, which were experienced as a result of the events that occurred throughout the relationships, were analyzed. The general dynamics of these dimensions as well as the patterns that are typical for different love styles were discovered. The application of methodology to analysis of individual change in romantic attachment during relationship is demonstrated.Keywords: attachment; romantic relationship; young adults; love styles Bowlby's theory of attachment explained the psychological nature of a child's bonds to their parents and the possible impact this experience can have on shaping future interpersonal relationships.

This became a popular approach to romantic relationship research (Fraley & Shaver, 2000).The quest for the study of temporal model of love became timely and attachment was a worthwhile candidate for such research (Berscheid, 2010). The recent research has revealed that romantic relationships gradually develop attachment characteristics over the course of a particular relationship and with age (Hazan & Zeifman, 1994). Wehner (1994, 1997) considered romantic partners to become major figures in the functioning of the attachment, caregiving, affiliative, and sexual/reproductive behavioral systems. Affiliation and sexuality are expected to be the central systems in romantic relationships initially, but gradually the attachment and
