Thanks to everyone for your thoughts and opinions and advice! I'm definitely not going to just allow this. I guess what makes me the angriest is the fact that ex husband knows how I feel..he knows about the child killed in the auto accident..and he just doesn't seem to care that my children's safety is more important than ANYTHING to me. It's for reasons like these that I have sole custody of my kids..he only has visitation rights. I think he continues to ignore the safety of the kids, I will do as suggested and discuss it with an attorney at the very least.
