<prompt> Human: So we recently found out by doing a credit report for my fiance that his mother has had for almost 10 years. It has a 3k limit and shes already at 1700 for this month on it. Its also been the only credit card on his name ever hes now 26. His credit is pretty good because she has been paying it and the like but...well the relationship has absolutely tanked, and she has abused him verbally, emotionally and while growing up financially too. She recently has escalated whenever nothing is going her way. We arent sure what our next step needs to be. I know we need to cancel it, but we dont want to be strapped with the final bill. He is a little concerned about going after her for identity theft.Any advice is super apperciated. Especially since this is stupidly delicate.  <response>: hes got to make a decision. its a card under his name being used by someone who is not him. can get the authorities involved with identify theft or if he wants to keep it delicate, talk to mom again and try to reason with her into paying it off and not using it anymore. if she doesnt listen, he can then choose to close the card and pay off the bill.he should absolutely freeze his credit with equifax, experian, transunion, innovis, and cheksystems.
