Well that explains it. You called the police and now he's behaving. Good for you! I never have the courage to do that - afraid my H would be more angry. But it has the opposite effect! They only abuse in private. They hate to be exposed.
You can file for D or Legal Separation - that should get him out. Write down all the instances of verbal and emotional abuse that you can remember or find in journals. Bring it to a lawyer who specializes in domestic violence. Sounds like this guy listens to authorities drawing a line with him.
