<human>: Can you provide a brief overview of the text?

I've been dating my girlfriend for 7 months and I know for sure that I want to marry her someday. Right now we're living several hours apart and only get to see each other about every 2 weeks. (I've known her for about 4 years in case anyone's questioning how I can want to marry someone I've been dating for 7 months and only get to see every 2 weeks). 

Almost every day, I have to fight off thoughts of something terrible happening to her before we can get married and start our lives together. I'm not exaggerating when I say I honestly can't imagine trying to fall in love with somebody else. I've known this girl for so long and built such a strong friendship with her before we started dating and now we have an amazing relationship and I don't know how I'd be able to continue on with my life if something happened to her. 

It would be different if we were already married and had children. If, god forbid, something happened to her, I would *at least* have our children to keep me going. But right now, if something happened to her, I'd have to someone move on and find someone else (which is unimaginable) or face a life alone (equally unimaginable).

Can anyone help me through this?
