"I've been doing some thinking, and I have decided that (four very powerful words, those -- remember them, as we'll use them later, too) I need some space. I'm questioning whether or not I want to remain married to someone who would treat me so poorly, and who would disrespect me so much that you would suggest I 'try out' for the position of being your wife for 3 months. You need to find yourself a place to stay, by the end of the week, because I have some thinking to do."
If I wasn't at work I could type some doozies.
Coach,
The thought of you in a dress just isn't doing it for me.
