Enmeshment refers to relationships that have become so intertwined that boundaries are nonexistent or identical. While this concept most often occurs between a primary caregiver and their child, it can also happen in romantic relationships. Although enmeshment can initially lessen worries around abandonment and rejection, ongoing enmeshment can lead to resentment and low relationship satisfaction. Reference: The Attachment Project You may ask how does enmeshment relate to trauma bonding? Trauma bonding occurs when a deep emotional bond is formed with someone who has been harmful toward you, and is often marked by repeated cycles of abuse coupled with positive reinforcement. The codependent nature of enmeshment makes removing oneself from a trauma bond extremely difficult and can lead to continuous patterns of abuse, neglect and abandonment.
