I know you appreciate what everyone has said but waiting until independent may result in you dying.
If your husband never before showed an ounce of this behavior when you guys were dating and in the marriage then this behavior is an explosive one and one that lead to him killing you. Also if he has shown you hints of this in the past such as getting aggressive and punching walls or grabbing you when angry, it means he was showing you what he's capable of. If you were my family member I would be saying the same thing because your life is worth so much more than trying to walk on eggshells to get to independence because you may not live to enjoy the independence.
Lifetime, ID, Oxygen and True Crime has so many stories like yours and we know they don't end well.
Sorry for being blunt but I work in healthcare and have seen abuse and women who are scared to say a word. So please take my advice and run for your life.
