You each just file your own tax returns. You are not going to be entering rent or utilities on your federal tax return. You are not filing your tax return together. You each can file as Single and enter your own income information.
There is not a rent deduction or credit on your Federal return. If your state has anything for renters you will be prompted to enter your rent info when you complete your state return. As far as I know, the states that have anything for rent are Arizona, California, Connecticut, Hawaii, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Jersey, Rhode Island, Vermont, and Wisconsin.
