Trauma bonding is similar to Stockholm Syndrome, in which people held captive come to have feelings of trust or even affection for the very people who captured and held them against their will. This type of survival strategy can also occur in a relationship. It is called trauma bonding, and it can occur when a person is in a relationship with a narcissist.
Within a trauma bond, the narcissist’s partner—who often has codependency issues—first feels loved and cared for. However, this begins to erode over time, and the emotional, mental, and sometimes physical abuse takes over the relationship.
The codependent understands the change, but not why it is occurring. They believe they just need to understand what they are doing wrong in order to bring back the loving part of the relationship.
If they do manage to break free, all the narcissist has to do is go back to that courtship phase to win them back. The more the codependent reaches out to the narcissist for love, recognition, and approval, the more the trauma bond is strengthened. This also means the codependent will stay in the relationship when the abuse escalates, creating a destructive cycle.
