A social network represents a web-based service allowing individuals to build a public or semi-public profile within a bounded system. Recently, the ever-expending influence of social networks on modern society has sparked intense debates about the positive and negative effects of using social networks. The aim of this paper is to present the positive and negative aspects of social network usage in romantic relationships. While criticisms frequently emphasize the negative effects of social networks on mental health, privacy, and relationships, positive effects of social networks on individuals' lives are also observed. By applying social exchange theory to the context of social network use in romantic relationships, one or both partners may perceive interaction through social networks as a reward based on emotional support, acceptance, and connection that they provide to each other through this communication channel. One of the main issues of the internet, further exacerbated by social networks, is privacy. Additionally, the wide possibilities offered by social networks can trigger jealousy for some individuals, while other concerns include digital boundaries and excessive use of these platforms
