I really don't know what to suggest, except that I can see how hard this is, and completely understand.
I was going to suggest being firm, and being clear about the boundries, etc, because sometimes people find that hard to judge. Is there any way you could get one of her family members to talk to her, and try and get some sort of message across?
Also, I think you need to be completely and utterly clear with yourself, and her, about how you want your relationship to be, if that makes any sense. If there's any sort of uncertainty on your part it is likely to make it even less clear to her. You need to be firm and consistent, I'd say.
Sorry to be of no use, but I hope it gets better.
