renewing licenses

I'm suppose to renew my license in June. I'm not sure if I should keep my moms address or my boyfriends. I moved in last year and we're excepting our first so no intention on leaving or anything. It's just I have a lot of stuff under my mom right now. And I don't pay any bills besides my own personal stuff and groceries, living with my boyfriend. So I don't even have any mail that gets sent to our house, so not sure how I'd even provide proof of me living there since I don't have bills being sent there. And I don't know what proof I have to have exactly of me living there besides mail but not sure if it has to be bill or something else?
