Yup. Pay your bill.Your spouse has the same right to the vehicle as you do. Your problem is that your paying nothing on the vehicle - so she has to pick up the bill. If she is paying the bill, then she deserves to have the vehicle. If you are paying the bill, then you deserve to have the vehicle. You cannot "one-up" your spouse by driving a vehicle that also has her name on it, and not paying for it. Your credit and her credit will suffer. My advice? Pay your bill. She has the right to the vehicle until you do.
