Attachment theory explains how early childhood experiences with caregivers shape emotional bonds and relationship patterns throughout life. The theory identifies four main attachment styles—secure, anxious, avoidant, and disorganized—characterized by different levels of anxiety and avoidance related to intimacy. These styles significantly impact adult relationships, influencing communication, conflict resolution, and overall relationship satisfaction. While attachment styles tend to be stable, they are not fixed and can be modified through positive experiences or therapy. Understanding one's attachment style can improve relationship outcomes and overall well-being.
