Co-dependence is a behavioral condition where one person relies excessively on another for emotional support, self-esteem, and decision-making. This often leads to an imbalance in relationships, where one partner may prioritize the needs of the other over their own, resulting in unhealthy dynamics. Individuals in co-dependent relationships may struggle with setting boundaries and may feel responsible for the other person's feelings and actions. This can create a cycle of dependency, where both parties may find it difficult to function independently, impacting their overall well-being and personal growth.
