Is She Taking Advantage of Me? Or Am I Going to Let You Steal From Me?

If she is an authorized user on your account, and not like a joint owner, then i would just go to the bank and take her off the account. But that does not mean that she should have free to go into your account, t your money and do whatever the funk she wants to with it. And even if im like moving your money or whatever, if that's too extreme, i think it could be worth it just say to her that you feel kind of like an object. You know, you feel am her andused. Well, now you know what to do yet?
