When my horrible husband died I would spontaneously shout out with glee, “You’re dead xxx!” He committed suicide. He intended to take me with him, but his plan failed. As a teen I lived in a haunted house. The two had nothing to do with each other. The point is I believe you. My sincere advice is to shit on his grave. Honestly. If you can’t do the act there, take it in a bag and at an opportune moment dump it. If he wants a fight, bring it on. And move to a house you didn’t share with him if you haven’t already.
