Oh - just saw where he makes you show him the grocery receipts.
Is there anyone you know who might let you "buy" their groceries for them and then give you the money? Hmmm, seems dangerous if you're in a small town, you'd really have to trust the person.
The way I see it, you may just have to wait until you have a tank of gas (does he let you fill it up?)and then just head for a shelter. If you don't have enough gas, you might just have to rely on the kindness of strangers once you get out of town.
Don't worry about taking stuff with you. If you have to leave with just the clothes on your back, so be it.
Can you take the kids to the movies? Some excuse to be gone with them for a couple of hours before he would get suspicious?
