Someone who was suppose to be a close friend has gone behind my back and is telling people things I told her specifically not to tell anyone. Is there a spell to stop her from doing this again? I don't appreciate my secrets and private life being made common knowledge, so I want to make sure she can never tell another secret about me, again. I would confront her about it, but I don't want her telling more, than she already has. It's already damaged some relationships with friends and family, it has to stop. Someone please help me.
