RSF, I cross posted before your last response. Note her actions right now after you set a boundary. Boundaries are healthy and loving. Your impulse will be to reach out to her right now. Let her come to you. She might be very upset and angry. Let her vent, you validate and don't match her emotions. Stand strong.
Cheers Coach
