This article aims to document the complexity of romantic relationships among youth experiencing homelessness. Using a qualitative approach, 42 youth experiencing homelessness (18 to 32 years old) were interviewed individually. The analysis reveals that precariousness in the context of homelessness exerts a tension on youth’s romantic relationships. If youth report the need to create romantic relationships to meet their emotional, material and identity needs, they nonetheless describe the impossibility of maintaining these relationships due to a movement of withdrawal into themselves for their survival. The context of homelessness highlights "the impossible necessity" of romantic relationships among youth.
