Relational needs include needs that help us maintain social bonds and interpersonal relationships. Communicating to fill our instrumental needs helps us function on many levels, but communicating for relational needs helps us achieve the social relating that is an essential part of being human. Communication meets our relational needs by giving us a tool through which to develop, maintain, and end relationships. In order to develop a relationship, we may use nonverbal communication to assess whether someone is interested in talking to us or not, then use verbal communication to strike up a conversation. Then, through the mutual process of self-disclosure, a relationship forms over time. Once formed, we need to maintain a relationship, so we use communication to express our continued liking of someone. We can verbally say things like “You’re such a great friend” or engage in behaviors that communicate our investment in the relationship, like organizing a birthday party. Although our relationships vary in terms of closeness and intimacy, all individuals have relational needs and all relationships require maintenance. Finally, communication or the lack of it helps us end relationships. We may communicate our deteriorating commitment to a relationship by avoiding communication with someone, verbally criticizing him or her, or explicitly ending a relationship. From spending time together, to checking in with relational partners by text, social media, or face-to-face, to celebrating accomplishments, to providing support during difficult times, communication forms the building blocks of our relationships. Communicating for relational needs isn’t always positive though. Some people’s “relational needs” are negative, unethical, or even illegal. Although we may feel the “need” to be passive aggressive or controlling, these communicative patterns are not positive and can hurt our relationships. In Chapter 6 "Interpersonal Communication Processes" and Chapter 7 "Communication in Relationships", we will explore the “dark side” of communication in more detail.
