•As Reis and Shaver point out, for a relationship to develop, as well as an increase in breadth and depth there needs to be a reciprocal element to disclosure.•Once you have decided to disclose something that reveals your true self, hopefully your partner will respond in a way that is rewarding, with understanding, empathy and also their own intimate thoughts and feelings.•So there is a balance of self-disclosure between both partners in a successful romantic relationship, which increases feelings of intimacy and. . . deepens the relationship.
