Flutie, I don't know what to say about the guest room. For me, it would have been only to complete Part One of the Exodus. That is, I wouldn't have done it to make a "statement". Because, after all, you are making that statement to your kids as well and you don't want to be jackin around with their feelings of security. In my mind, I had a series of events that would happen if the marriage were ending (or, in my case, I was moving out--he would never go for a D) and that was the first one.
I would NOT do it as a way to get his attention. Let your actions be those of someone who acts out of love and integrity. If you don't feel loving and like getting up and cooking for him, don't do it. He WILL adjust. The temper tantrums probably won't last for more than a day or two.
In fact, I think doing things like this will get his attention faster and more effectively underscore what you're trying to do than moving into another room.
