Agree with the others stating to place his items outside. Do not invite him in. Do not engage him. Call the sheriff and have him there to monitor the pick up. Then keep your head on a swivel till you know he's out of town again. I would also consider a restraining order. Document EVERYTHING...including his contact informing you he was coming to get his stuff. Everything. Also...if you have a friend that has a big dog that you could borrow for the time...that might also be good. As well as "anything" you think you might need to protect yourself. Prayers are with you!
