I used my girlfriends atm card over the week end with out permission. But she has let me use it many times before, we have worked things out and she agreed to just let me repay her and i will asap. her account wasnt over drawn or anything and she still has alot of money in there. My only concern is the bank coming after me and if they do what is going to happen?
If your girlfriend doesn't press charges, I'm sure you will be fine. Try not to take people's things without their permission, okay? You won't have these issues if you think things through.
