You have been given excellent advice the last day or so. You don't have to deadbolt the door, but you can leave it ajar or just firmly shut it for the time being. Trying to talk to someone who is operating on pure emotions is only going to frustrate you even more so. You, and only you, can decide when you've had enough the frustration and leave him to himself and move forward w/your life.
Leave your life to the fullest and act as if he's not coming back. The best revenge in all of this is to live a fulfilled life.
