Despite the recognition that technology is ubiquitous and critical in modern interpersonal relationships, little is known about the meaning individuals assign to their close online relationships. Furthermore, there persists a negative bias towards online relationships. This study, using a sociocultural approach, sought to address this gap by qualitatively investing adults’ lived experiences and processes of meaning-making in online relationships. Specifically, we sought to identify common dialogical tensions in participants’ discourses as the moments when meaning is created and negotiated in dialogue with the medium and cultural context. Thirteen semi-structured interviews were carried out in-depth with participants who had diverse experiences of close online relationships, including romantic relationships, dating, familial relationships and friendships. We assumed that the distinctiveness of this research design would highlight the interconnectedness between different types of relationships. Additionally, we expected more pronounced levels of tensions among close relationships enabled by technology. Through the analysis of dialogical discursive tensions, we identified four main tensions in the discourses: opportunities/constraints, authenticity/staginess, safety/risk and proximity/distance. The latter emerged as a fundamental tension, intertwining with other tensions, and prompting reflections on the realness, depth, and validity of online relationships. The analysis unveiled that individuals' experiences with online relationships are shaped by the actual use of the medium, societal representation of technology, and cultural discourses. Often, these cultural discourses and representations contrast with individuals' lived experiences, contributing to the tensions. Navigating these factors poses a significant challenge for participants as they negotiate the complexities of online relationships.
