I just sent him a text saying I wouldn't be around tonight due to prom errands (prom is tomorrow). I also gave the email to my atty, maybe we can arrange for a meeting with the four of us- me, stbx and each atty. That will definitely piss him off hugely and he'll remove himself from my life except for kid issues.
Honestly, that sounds like a HUGE step in the right direction.
