My group of friends have a member of it who has a grudge against me, Every time I talk just getting dirty looks and online telling me to fuck off after every thing I say. He's told mutual friends that he beat me up and various other stupid lies to try and turn others against me. I've begun to push my friends away because I don't want to be with this person and personally I think that due to the fact it's just him being a dick the least they could do is tell him to knock it off but they're apathetic and just say he's like this with everyone or other dumb excuses like it's just to you so they don't want to do anything. Am I correct in desiring he gets some comeback or AITA for pushing away my friends due to this.
