I think it is good that you are aware of the danger. I'm sorry to say that when my mother told my father she wanted a divorce, he actually sat her down with a gun in hand and played russian roulette with her. He spun the cylinder pointing the gun at her first and then himself. It went off and killed him. It was front page news in San Francisco. Needless to say, my sister and I have suffered emotionally ever since. That was 50 years ago and I still can't forgive him. I think I might research for a Hot Line that may be able to provide assistance and guide you with leaving the situation. Good Luck and you'll be in my prayers.
