I once had this type of friend. I cut my realtionship with her and yes, it was one of the best decision I've ever made. She became a criminal and she would drag me (and other friends) if we didn't ditch her.

I suggest you to do the same. Don't be afraid of confrontation because you can't leave her if you don't confront her. Show her that you can't be manipulated. You can just block her contacts or avoid her. If she send you hurtful messages, counter back with proofs and criticizes. Narcissist can't handle them. Eventually, she will leave you after realizing that she can't use you anymore.
