Advice

Hi um I'm 16 and my boyfriend is 18 and he just graduated. He's so sweet and isnt pressuring me into anything because he knows I'm not ready. He said he'll get an apartment ready and everything so I can move in with him after I graduate. He told me he'll wait for me if I go to college somewhere other than at my home town. I don't know what to tell him or what to do should I ask him to come with me if I do choose to go somewhere else or should I let him stay if he wants. I know this is pretty stupid but I'm kinda stuck on what to do.
