kj. Did you tell the cops he was smoking crack and is suffering from drug induced psychosis! Just call them everytime he shows up. Don't be discouraged. Whether or not your husband physically threatens you, call the cops if he shows up and tell them he is suffering from drug induced psychosis and you are scared. Crack makes people crazy. That is why he's acting like a lunatic. Eventually, he will stop coming over, but you must keep calling the cops. Good luck.
And it is good to be a little afraid of someone who is smoking crack and acting crazy. At the very least, you should be a little afraid of him. People who are high on crack can become dangerous without any notice. They can just flip out because their brains are all messed up and you don't know what they are thinking.
