I'm single myself and was asked about that a couple of times. While I can't be sure about the exact intention of the interviewer, I know in one case one was trying to learn about my support system as I would have no family withing a 1500 mile radius. Another one felt that having a spouse could put strain on a student and seemed pleased when I told him I was single. Foremost I believe that the most critical thing adcoms are gauging in an interview are the qualities of your character (maturity, sense of responsibility, etc.) and I don't think that your marital status plays a significant part, if at all, in their decision. In regards to obtaining a spouse during the next two months to impress a panel of aged professors - my instincts say no. Best of luck!
