Ok so i am dating this guy who is about to go into the navy. I live with him and everything. I feel as if im floating on the clouds when im around him. I mean, he is a good guy and all but i dont know if i can handle him being gone all the time. I've told him i loved him and he said it back. but what if things change while he is gone over seas and everything with the navy? We also talked about getting married and everything but what if when he gets back or while he is gone things are totally different between us? What am I to do? He is only 19 years old and i am 20. is this a big mistake or is it meant to be?
