I think you need to think very, very hard about what kind of relationship is best for you and your daughter with someone who are repeatedly describing as manipulative. If it's something you both can handle long-term that's ok, but manipulative people (bipolar does not make us manipulative typically btw, maybe at some points in mania but manipulation is not a hallmark of this disorder (although it does go better with borderline personality disorder which I wonder if you are describing because there can be a push/pull patterns to relationships with BPD involved and it can be hard to distinguish from bipolar sometimes) are hard to deal with and can hurt you over time. If this is psychosis it's not really manipulation because she'd have to be capable of thinking out how to manipulate and I don't think that's possible. Maybe while manic in a more euphoric way than I know about.
