As opposed to most of the studies that discuss the issue of late singleness from a sociocultural viewpoint, this study examines the possibility that such a status is actually connected to endogenous factors, and the individual's internalization of his parents - specifically the relationship patterns between them. Eighty-one single and married respondents aged 25-40 answered a detailed questionnaire based on the Object Relations Inventory (ORI) (Blatt et al., 1988) and adapted for the current study, and that included the attitudes of the respondents to how they viewed the mother figure, father figure, partner figure, and self-image, as well as connections with parental figures and a partner. We presumed there would be differences between singles and married participants in their primary and internalized object-related relationships with parental figures and their relationship with their partners. The results of the study pointed at the differences between singles and married participants regarding the level of conceptualization, and the perception of the parents’ characteristics and the connection with them. The significance of the influence of object relations on late singleness and marriage is discussed below.
