I am sorry you are going through this with your ex, I would definitely call the police and have them pay him a visit, You said he hates the police, Then I would especially call them and make a report, I think he is just trying to scare you with his threats because he didnt get his own way, He is just full of idle threats, And I would definitely get a PPO on him, He will not be able to contact you in any way shape or form, Including trying to bring anything to your place and dropping it off, It will be breaking the PPO if he steps near you or contacts you and I dont think he wants to go to jail, Good luck and dont let him intimate you
