<prompt> Human: In Delaware, if that matters. Long story short, she signed as a co borrower on a 2 year old car from Carmax for her boyfriend. He has become estranged and she isnt sure how to proceed. He bounced a payment last month but he assured her he took care of it.  <response>: She legally bound herself to pay for the car if he doesnt theres really nothing much she can do as far as I know.
