only advise i would have is to make sure that she realizes what u do and what goes on with your job. i wouldn't suggest doing like i did and marry a girl u knew before you flew. she finds it hard to adjust what she wants/expects from me. in a way we have to change our relationship.
also, if u can marry a girl with a good job and makes good money, do it. life goes much easier with that additional income. fo pay isn't so bad when the better half makes 60k/year out of college.
i would say get married. as long as u can keep it in ur pants when ur away from home u'll be alright.
