Can you legally date or move in with your boyfriend if you are 16 and he is 23?

I'm assuming that you can if you have your parent's consent, and full permission to do so. However, if you do not get your parent's permission, and you move in with him anyways, or continue to date him.... whatever the circumstances maybe, he can get into some trouble, because you are 16, and he is 23. But before making such a big decision, make sure you know what to expect, and that you'll be able to accept all the responsibilities that come along with all of it.
