I’d agree with the others - it’s a good idea to consult a lawyer, for many reasons. Take important documents and leave copies with him. Maybe it might be a good idea to schedule a day off yourself on a day when your husband will be working again, if at all possible, so it’s easier to get organised. If he is generally violent/abusive, document the incidents of that behaviour in as much factual detail as possible and keep your notes safe. It might prove useful later.
I’m sorry you find yourself in such a position where you have to pack up and leave in secret, but I wish you the best of luck, and I’m glad you have somewhere to go.
Have you considered a camera doorbell for your new place? I don’t think you need to tell him your new address, but if he does find out that could help keep you safe.
