I think you should do what you and your boyfriend want to do. Do what makes you both happy. Don't worry about what anyone else thinks. BUT (you knew there was gonna be a 'but', right?

) it doesn't hurt to protect yourself in the event of something going wrong, no matter if you're living together or if you end up getting married. Marriage is no guarantee that the relationship will last forever. I wish you the best of luck in whatever you decide.
