Dependent personality: 

Definition:

Persons with this disorder surrender responsibility for major areas of their lives to others and allow the needs of those they depend on to supersede their own needs.
They lack self-confidence and feel intensely insecure about their ability to take care of themselves. They often protest that they cannot make decisions and do not know how or what to do. This behavior is due partly to a belief that others are more capable and partly to a reluctance to express their views for fear of offending persons they need with their aggressiveness (ie, a form of aggression against self). Dependency occurs in other personality disorders where it may be hidden by obvious behavioral problems; eg, histrionic or borderline behaviors mask underlying dependency.
