Good job on setting some boundaries. Do NOT move out of your bed, whatever you do!
Ordinarily, I would say that a wife who is running away from her family has no right to know where you're going, but she may just be genuinely concerned that you may be drinking again. Maybe you say something to her like "Look, I appreciate your concern, if that's what it really is, but since you're running away from our marriage right now, you really don't have any right to ask me about my whereabouts. I'm not drinking, if that's what you're worried about. Now, I need to go (insert GAL activity here)."
Please do not equate being a busy SAHM with not having time to have at least an online EA. With the "wonders" of modern technology (AIM, Facebook, etc.), it really doesn't take much, and she sounds pretty fogged-out, to me.
