I will pray for you that you have the courage to walk away from your husband. you should not continue in such unhealthy relationship. He will destroy you. You should pray for him to quit his addiction but in the meantime you should move on with your life away from him. God would not be happy with your supporting this relationship. Drugs kill people and every one around them. Rebuild your life away from him. When he quits and he wants you back, then you can consider it. I will pray that God gives you the strength and courage to begin a new life.
