Thanks, everyone. Being able to come here and read, and post, and vent over these past couple of months have made it so much easier to just let the crazy at home roll right off my back.
I still can't believe he's leaving in the morning. I will actually be able to prepare for the move now (before I planned to not really pack anything in advance, knowing it would set him off into a rage). My little guy will be able to enjoy his first week of school in a peaceful environment. I am prepared to have to deal with him for a day or so before I move, should he arrive home before the 31st.
