Like-minded ladies

I've made the decision to move out of state. But my only issue is that the father of my kids doesn't think like me. As a woman, I want to feel safe and make sure they will be too. I don't believe that I will stay safe here in the south. Every week, it's something new they are dismantling. I'm worried about the DOE being closed. I've gotten off topic, so I told him my plans to move, but he has said they can't go out of the state with me. We never went through the court. I can leave and they will be able to visit me. Told me they couldn't live with me once I'm settled. So my question is if I do move and he still says they won't stay with me. Can I get a family lawyer involved? Would my case win?
