Sometimes relationships that were once close can experience conflicts, minunderstandings and betrayal. When this happens, estrangement can occur. Estrangement refers to a state of separation, distance, or alienation between people resulting in emotional and physical separation.. Whether as family members, friends, or romantic partners, this type of separation can be damaging to all involved. Reunification therapy is about helping individuals come back from this type of disconnect. The goal is to facilitate a gradual, structured reconnection that promotes emotional healing and a more stable, positive relationship.
