Moving in?

My boyfriend and I have been dating just over a year, we did long distance for 6 months before I moved to his town into my own place. We are both turning twenty and are considering moving in together in a few months when my lease is up. I know his family thinks it too soon but I've always been quite a bit mature for my age and have been independent since I can remember. I just wanted to know other people's thoughts I guess. Even though I'm sure we are going to do it anyways because that's just who we are haha .
