What a trainwreck,... it's hard to be positive with the info you are giving us. Your girlfriend comes off as immature, manipulative, energy sucker, blackmailer, etc... By indulging into her, you not only are not helping her, but continue to lock her into this deadlock of passive-aggressive way of relating to others.

The interesting aspect about this is why are you still going for this relationship? She is simply not fit to have a boyfriend at the moment, why don't you let her sort out her issues and come back, if she's still interested?

I only see lots of pain in store for you and her in the future. But perhaps this is for the best, you are maybe the kind of guy that needs this kind of clingy girl to feel relevant... Maybe it's rather you who needs to sort himself out, before thinking about her case?
