Unreliable partner.
The unreliable partners shift responsibility for their lives to others. So the OTHER has to take care of them, meet their needs, think of them, and share some resources.
Even better if he or she gives ALL the personal resources.
The unreliable people tend to blame others, make claims, accuse, insult and force the victim to act in a way contrary to their own interests, demand, as well as appeal to the other's sense of duty, covering up their own plans that way.
Such a person will never discuss his or her goals, since to achieve something, one should give something away. And the unreliable partner is not going to lose anything he or she owns. That's why manipulating others is hidden by the words "you have to", "everyone lives this way", "it's hard for everyone", "you shall"
