In this article I am trying to perform an analysis of the family life experiences of cohabiting couples. I used narrative interviews done and recorded as part of doctoral dissertation about cohabiting relationships. The analysis of previous research results showed that cohabitation is a more theoretical construct than models implemented in real life, and experiencing cohabitation, in spite of universal knowledge, still remains vague. The phenomenological perspective that I have chosen, different from other ones in terms of methods and ways of research, allowed me to understand meanings, values and entities, which describe living in cohabitation. This study connects situational data with life experience data, and combines experiences in such a mode which reflects the fullness of human background. In order to write this article I made an attempt at clarifying experienced, understood and interpreted cohabiting couples’ spheres of family life and processes of experiencing it while building family reality, with emphasis on the significance and meanings which respondents give to their common life. I have chosen these aspects of experience which pertain to the perspective of experiencing relationships that I have defined, that is, to the meaningfulness of family life. Reflections presented in this article are closer to the logics of family transformation discourse, which says that the modern family adapts to social life conditions; it increases its diversity and complexity, not its atrophy.
