You need to tell the court your fears and do everything you can to get them. I don't know being the mother and him the father if you could get a restraining order on him when he bring's the kids. Get a lawyer and def. fight to the end cause he should not be with them just remember that you will need tons of proof. Try to get him to stay even two days and play silly. Get a notebook and keep every bad thing he says or does written in that notebook so that way when you fight for the kids you have that book and they can give him a lie detector test and he is busted and you have the kids. You could also try to get him to say he doesn't love the kids and get it on a recorder. Some states allow it I don't remember if Jersey does or not in court. Good luck with everything! Hide the notebook under the mattresses...
