It isn't clear to me if you are a graduate student in training to become a therapist and if so, when you say you "see" this woman do you mean in therapy? If so, your clinical supervisor could help you arrive at a diagnosis. But no therapist should diagnose someone in absentia i.e.without seeing them face to face in a clinical setting.
If you are not in training, you can certainly get opinions from advice columnists on other people's behaviors and how you should respond but I don't see this as that kind of forum.
