Does the gallery have security people they can call in for the Friday event?
Is there a way you can attend the Friday event and still feel that you're safe? Do you have any really oversize muscular male friends that you can bribe with dinner to be your body guards for the night? If not you, do you know anyone who knows anyone?
I hired a friend's 21-year-old son (straight from an Army tour in Iraq) to hang out on my couch for a couple of nights after one of the times AXH threatened me. Nothing ever happened, but it gave me a sense of strength to know that I could do things to protect myself.
