Narcissistic enmeshment is a type of relationship dysfunction in which one partner excessively relies on the other for affirmation and self-definition. It is most commonly seen in relationships where one partner is narcissistic and the other is codependent. The narcissistic partner demands constant attention and admiration, while the codependent partner gives up their own identity and becomes obsessed with meeting the needs of their partner. This leads to a cycle of dependency and abuse in which the codependent partner is never able to get their needs met.
