Pisces bully
I don't know what he is thinking or why he would act that way but I think the best thing you can do is not waste your time worrying about someone who is not treating you with respect and kindness. Try to focus on the good people in your life instead and don't play into to his childish game. Sure some Pisces people will have some more specific advice but that's mine, good luck Hun, hope it gets better xxxx
