I am so sorry for what u are going through. I also fled domestic violence and my husband took all 4 kids and hid them at his family house while he filed for divorce and custody and then left me homeless...9 months later I finally have joint custody but I get no help from the state or even child support cause the attorney that finally agreed to help me a month before we went to court did a half assed job and did not have my back at all. It’s hard but hang in there and best of luck to you! I would suggest getting an attorney if u can and make sure u document everything
