<human>: As the title states, girlfriend of 4 years is gaining the courage to join the
military, Air Force to be exact. She wants to see the world and help
 people and potentially use her degree(bachelors degree in sociology) 
We are both 29 years old and though I feel I'm always supportive in her decisions, this decision she is making has me somewhat on the fence. I have heard and read horrendous stories(thanks reddit /s) about relationships when the boyfriend/girlfriend or husband/wife is in the military. I'm using google to see how long the process is(basic training, schooling, deployment, etc) but I would greatly appreciate ANY advice regarding the matter. I don't want to go in blind with her choice that can also effect the relationship in any kind of harmful way. As stated we have been together for 4 years(both are longest relationship) and she wants me to be with always(marriage is on the table) but what are the rules or policy for couples dating to a married couple? If she is deployed to germany can a boyfriend accompany her or is that an option for married couples? I sincerely love this girl very passionately but i would be lying if I say I wasn't afraid that her choosing to join the military might come in-between us.

Can you provide a brief overview of the text?
