It seems to me like he is only "helping" you because he expects you to yield to his advances or to lower your guard and not take legal action against his harassment. Whatever "good" you see in him is probably a facade, and he could very well get tired of trying to win you over and somehow set you up in a way in which you lose your job, reputation, etc.So this issue has now been definitively resolved. Last Tuesday I was urgently summoned by the director for an interview.
First he apologized for his various behaviors, but then he started to resent me for not being nice enough to him and felt that I was irrelevant to him and his vision and mission. Then he asked me to stay and at least have wheels. I agreed to the classes, but I signed my resignation as a teacher by mutual agreement.
Before I left, he asked me if he could touch my hair, but I said no, so he didn't touch me.
I would try to minimize contact with him, try to record interactions, and plan your way out and maybe stay with the students as a private tutor separated from school activities if you really want to keep a connection with them or something along those lines.
