Hexes - Can they be put on someone even if they have done nothing wrong?

Hello - I have a question about hexes. Can someone place a hex on you if they feel you have wronged them, even if you haven't? I have a person I met through social media who claims I ghosted them at an event, when I did nothing of the sort - I simply didn't see them. I'm often in my own world & wouldn't notice the most obvious unless it was pointed out to me. So because of her hateful words about it to me, I blocked her on social media & will no longer have anything to do with her. This is the second time she has gone after me for something I did not do & I just don't want to have that drama in my life anymore.

So can she really hex me even if I am in the right & have done nothing wrong? Is there a way to protect against it? I'm not sure I really truly believe she can do this, but I don't really want to have any more bad luck or misfortune come to me or my family this year.

Thank you for your help in this.
