I had the same issues with my first wife. At one point when we were separated she attacked me in public and tried to steal my keys so she could take my car, while I was holding my kid. I had scratches all down the arm that wasn’t holding my child, and I ended up retreating into a store, where she continued to attack me. When the cops showed up I was immediately cuffed, and she was treated as a victim, despite onlookers and even her telling them that she had attacked me. I would have definitely gotten booked except that a female officer was called to talk to her, realized what was going on, and made the male cops uncuff me and arrest her instead.

At the hearing for a restraining order the judge literally laughed, and gave her partial custody of the kid with no restraining order for either of us, and the local DA let her off with anger management courses and nothing on her permanent record.
