My boyfriend was charged with stealing my credit card but I authorized him to use it. Where do we go from here?

In order to solve the problem, your boyfriend's lawyer needs to get an affidavit from you or ask you to make an appointment with the Victim Advocate at the DAs office.  Tell the VA what happened and the lawyer will get this info to the ADA handling the case.  Depending on the county, the case should be dismissed.
