I am currently living with a roommate and the lease is up next month. After the lease is up, we are then on a month-to-month so we are no longer locked in to another lease. I am planning on moving out soon, however, most of the items that were purchased for the apartment were on my roommate's credit card. I haven't been helping pay their debt down, nor have I agreed to verbally or in writing. Short question is--when I move out, am I under any kind of obligation to help pay THEIR debt from buying stuff they wanted for the apartment?
