My ex-husband forwarded custody information to my employers?

I just won a big custody battle against my ex-husband, and he's very vandictive... He's extremely controlling and has a lot of foolish pride. His grief is unfortunately not for his daughter, but rather for his own bruised ego. I usually let things go because i feel that it's not worth the hassle. However, this time, I had a legitimate scare. I was sure he had hacked into my email accounts because he forwarded email conversations between me and him (regarding arrangements for my daughter) and copied a large portion of my friends and contact that were in my email account. I wasn't upset because the content wasn't damaging- for me at least, but I was upset thinking that he had actually gone THAT far and started think what other information he had. However, upon further research, in 2009 I sent an email-virus warning forward to about 30 contacts, including him (THE ONLY TIME I DID IT too). This issue is this: he ALSO emailed my EMPLOYERS this PRIVATE information. I was going to file for a PPO- because I think that besides that he's purposely harrassing me, he's trying to sabatoge my employment- he knows what emails my employers have because of the court case. The referee of the court acknowledged in her reccomendation that my ex has anger management issues. Is this grounds for a possible PPO? Please advise. I only want this type of behavior to stop.
