It's commendable that you want to put this matter into perspective, and that you want to have some power on your side mainly by developing a career and having your own business and property. Lack of power has been your undoing so far.
You have however not succeeded in having enough psychological and spiritual power not just over your husband, but in the world of relationships. So, just running won't do you any good. You need to learn how to fight, and dance, and control a relationship.
First, inspect your support system. Prepare your allies, direct your studies and research to your soul's nourishment, and get some space by way of a seperation. Then enlist the help of an appropriate therapist. For you I recommend family therapy and object relations therapy.
You must be strong enough to hold against this 'bully' so learn some self defense technique like Muay Thai, and be ready to use the law and police to your advantage.
Take the responsibility to heal yourself and your children, set standards that the man should fulfill and negotiate your way to freedom.
