You need to petition the court for a Protective Order. The granting of one should be a no-brainer for the court. I don't understand why the law enforcement officers who arrested him did not help you get a majistrates PO. Contact your local police and see if they will help. If you cannot afford an attorney, get with the local legal aid office. Sounds like what you need is a divorce attorney who would probably help you get a protective order and a restraining order as well concerning property.
I believe the abbreviations stand for "Injury to a Child Elderly or Disabled Individual with Bodily Injury." Your county should have a website that will allow you to look him up to see when his court appearances are and possibly a release date.

I agree that you should try to obtain a protective order. Contact your district attorney or county attorney and ask for victim services. These folks will steer you in the right direction and provide helpful information that is specific to your county. Good luck.
