Wow, that sucks! Could you have a conversation with your district's superintendent or asst. superintendent? Do so in a low key, non-threatening way, and just 'explain' what you have explained here, and ask for his/her "advice" on how to proceed from here.
All of us, at one time or another, will have conflicts with people at work. I actually ended up quitting a job after being sexually harassed by my supervisor.

I should have reported him, but i was very young and afraid it would harm my chances of future employment. Funny thing was when I quit at the end of the year, he was pissed off.

He should have been relieved that I didn't take him down!
I was hired immediately by another school. The way I handled it was to have other very good references from the same place... and i was ready to succinctly explain (without any details) why I chose to leave. I didn't use his name, just his position. It has never been a problem and I have worked in many places since then. Good luck and don't let this discourage you. Let us know how things go...
