Moving...

Okay so me and my boyfriend have been together for almost 5 months now. We met online. I know that sounds bad but I don't have a problem with it. He is 16 and I am 14. He always tells me that I am the girl he wants to marry. I am is one and only love, etc. He said he wants to be with me forever and he is tired of not being here with me. About two months ago he gave me some shocking news. He has got an emancipation and is moving half way across the country to be with me. I am nervous about it because we are so young. I'm scared we are taking things to far to fast. I am just now a freshman in high school and that is stressing me out, and now I have this. I don't know if we are moving to fast. Please give me some advice! Thank you!
