At first glance, she sounds like a manipulative little hm-hm-hm.
It is possible that she had a screwed up childhood and never really learned how to love and show affection properly, just how to take advantage of people who are trying to help her.
There's nothing you can really do with people like that except cut the ropes. At some point in their life, they have to learn that they're driving people away and they'll have to change their behaviour. Or else they won't, and they'll just die as the same miserable SOB's they were when they entered adulthood.
