Magic Forums

So I started talking to this weird guy on Facebook and at first we were like talking and he was nice then I was told to say an incantation (she called it a trigger, by a woman who said she was a friend of his wife's) because he was under a spell and it was supposed to make him "Show his true self" (I guess the being nice was an act so I could lift the curse from him, which I didn't) he keeps messaging me and telling me I'm "dead" and he's "Going to get me" Should I be worried about him casting an magic on me or anything of that sort? I wasn't worried before but I have anxiety and he is getting into my head somewhat. Any ideas/tips/information? Thank you so much in advance. Feel free to PM me if you like about this or anything else.
