It's too bad he's leaving you with even more work and expense on his behalf. To get around the expense part and what Seren just pointed out (GOOD point, Seren!) why don't you give him the date that it will all be put out in the driveway and he has until X o'clock to pick it up or it's GONE. That way he won't be in your house and in your stuff and in your face. You can lock up the house and be GONE during the window of time you give him to pick it up.
