Codependency
（重定向自Mother Hen）
Codependent relationships are a type of dysfunctional helping relationship where one person supports or enables another person's addiction, poor mental health, immaturity, irresponsibility, or under-achievement. Among the core characteristics of codependency, the most common theme is an excessive reliance on other people for approval and identity.
