My ex and his new live-in GF fight A LOT in front of my child(child tells me this and that it scares him). He also said she kicked him and father out of car on the side of the road once during a fight and they had to walk home. The GF has also caused a scene at his school in front of parents/kids and called me a name. I know they constantly bad mouth me and talk about matters in front of child. Can I file anything(order of protection, etc) to not allow HER near my child?
