<prompt> Human: I moved three states over in July and before I left I called the power company to set up a transfer of service. My ex roommate and ex friend agreed to call the power company to complete the transfer. I received a letter from a debt collector trying to collect on the 3 month delinquent bill. I called him and he assumed I was being generous by paying the bill. This escalated into him admitting he was bitter about our housing arrangement and felt it was more than fair I pay his power bill. Our arrangement while I was living with him was I paid all the bills and he didnt charge me rent as he was the homeowner. This I felt was fair as the average rent in the area was comparable to the cost of the bills. How should I deal with the debt collector and the potential hit to my credit?Edit: I dont have enough money to pay the delinquent bill so itll have to come out of my credit card if I pay it.  <response>: How should I deal with the debt collector and the potential hit to my credit?Pay the bill.
