adams- interestingly, all of us here who have mothers like this are suggesting avoiding the police though, and to rather find a mentor, rav, coach, psyc… I do think that says something.
byg- rabbonim do do that sometimes to avoid starting a shmooze with a girl. If you’d call him on the phone, even anonymously, i think you’d find him acting differently in that setting. If you are comfortable with how the convo goes, you can later say who you are. Also, how about his wife? btw, after the reaction you said your principal gave about bullying, i wouldnt go to her with your home situation even if she did have time.
