The truth is I have no idea how to help you friend. You only have three options: 1, - He get along with your ex, that I do not think that happens true. 2, - Putting your case in the hands of a lawyer. 3, - Get as far away from her as possible, freedom is a gift to take advantage of.
You should ask for a supervisor. Or write City Manager. I am an old lady and handicapped and every time I needed help from Stanton police (Sherriff's deputy) I was chastised scolded and threatened. Example, car accident police officer said to lady who hit me, if you have $500 just give it to her. Lady said she did not have $500. I said no I am going through insurance officer said are you hurt I said don't know yet and he started screaming so loud I thought he was gonna hit me. He said looking at the damage to my car that it was nothing and don't try to make a big thing about it Ends up it was damage in the tune of $3000. I needed chiropractor treatment. Lady admitted she was at fault I have more horrible stories to tell
Gotta get a lawyer or go to court house and ask questions on what forms to fill out.
