Do i leave with him or say goodbye?

Usually in relationships im very distant and although I care about the guy I always know things arent gonna last forever. But for the past couple of months I've been dating this guy and things have been completely different... I've fallen for him pretty...

hard, and although I've loved another before, nothing compares to how I feel now. For the first time ever I'm scared of loosing the guy I love, when usually I either feel theres no chance he'd leave me or I know that if they ever did id get over it pretty quick.
And recently his told me his planning to move like 700 miles away. His asked me to move with him, and every bone in my body is screaming yes, but well I'm only 18 so I dont want to be younge, careless and make a huge mistake. It's okay as he has family where his moving too where as I will have no one apart from him and his family. I love him and dont wanna loose him and I'd move to the moon if it meant I could be with him. This guy has made me the happiest I've ever felt and I'd do anything to mae him happy. He tells me he loves me, treats me right and is always wanting to do things for me. I dont want to be with out him. I just want some peoples opinions on whether they think its far too soon to make that sort of decision.

Honestly: you have to go out on your own sooner or later. Many of us desire for it to be as easy as it seems it would be for you. It's scary being away from your family for long periods of time, but if this man is as good as you say he is, then he would be very supportive of you, and help you adapt as well as possible.
