Considering there are different perceptions of what characteristics a person should possess in a particular social role, such as the role of a partner, couples engage in love relationships with a wide range of beliefs related to romantic relationships. Beliefs about love relationships are a reflection of the cultural norms of the prototype of presumably ideal relationships, but it is still considered that the experiences and knowledge gained in the primary family are the basic source of these beliefs. Therefore, the aim of this study was to examine beliefs about love relationships in the context of the dimensions of attachment to mother and father. The study involved 280 participants, of whom 42.8% were male and 57.2% female aged 18 to 33 years. As a measure of beliefs about love relationships two subscales were used, Disagreement is Destructive and Mindreading is expected of Relationship Belief Inventory (Eidelson i Epstein, 1982; Jakšić, 2018) and for the purpose of examining attachment to mother and father Relationship Structures Questionnaire was applied (Fraley i sur., 2011; Soldo, 2016). On average participants were not found to significantly differ in believing that disagreement was destructive and that mind reading was expected with respect to gender, and in belief that mind reading was expected with respect to relationship. However, it was found that participants who are not in a relationship, on average, accept the belief that disagreement is destructive more, than those who are in a relationship. The analysis of the results did not reveal a statistically significant interaction effect of gender and relationship status on irrational beliefs about love relationships. Furthermore, participants did not differ significantly on the dimensions of attachment for mother and father with respect to relationship status, and on the dimension of anxiety in relation to mother regarding gender, while for other dimensions differences were found. On average, men score higher on the avoidance dimension for the mother, and on both dimensions when it comes to the father, compared to women. Also, participants who accept more the belief that mind reading is expected achieve lower scores on the avoidance dimension for the mother and vice versa, and participants with a higher ranking on the subscale Disagreement is Destructive have a higher rank on the anxiety dimension for the father and vice versa. Other correlation coefficients were not found statistically significant.
