Question about Girlfriends of SF operators

[Hoss]

Hey guys. I've been tooling around this site for quite a while... by far the best source of information I have come across yet. I have been graduated from college with a Criminal Justice degree for a year and am pretty seriously considering enlisting with an 18x option. I have been dating a girl going on 3 years now and she just graduated college in May. We are moving out of our college town, and are trying to get out lives together and figure out what we are going to do. I was really hoping to get some advice on what to say to her to help ease her extreme fears about even talking about me enlisting. I have read the stickys and the link to the families, but I know as just a girlfriend, there wont be able to relocate her or anything like that. I am also curious about how much communication, and what kind, I will be able to have during training, the Q course, and after while on delpoyments. How much time would I realistically be able to see her if she doesnt live on base? Would I be able to propose and have time to have a wedding during the 5 or more year contract? Any advice or experiences would be tremendously appreciated.
