Well... DocJohn has an article, in PC's archives, titled: "You Can Only Change Yourself". Here's a link:

You Can Only Change Yourself

And, assuming DocJohn is correct (is there any doubt?), then you can't change your husband. Only he can do that for himself. And if he won't then the ball is in your court, as they say. Perhaps it's not a matter of you figuring out a way to get him to leave. Perhaps it's you who needs to figure out a way to do the leaving if it's that important that it happen. At least that is my thought with regard to your post.
