1. don't look for an argument because she is right now matter what according to her. i tell myself, "this time I am going to stick to my guns." Five minutes later, "i'm sorry baby."
2. just give her your wallet, without the credit cards and hope she leaves you $20 for gas money.
I can't tell you how mant times I have had money in my wallet and go to pay for something and mysteriously the money is gone, Then, there I stand holding up the line paying for $5 worth of stuff with a credit card. I feel like such an anchor!!!!
