Some advice from those in the know...
I was in touch with a retired SF Chaplin for a bit there, his advice...
"Just let her always know that you love her more then the job..."
(You could be rude here and say
"...and make sure she doesn't catch on you're lying")
I like what 18DWife said - This Chaplin put it this way
"She must see SF as her mission as well, if she doesn't she will only see it as something competing for your affections"
Another thing he said was
"Find a woman who understands that marriage isn't designed to solve all her problems and that a marriage is strong when it has a mission to focus on other then itself"
I like the Marriage with a mission way of thinking about it...with the BS Hollyweird culture of "Get married and you've arrived in life" everywhere you look, un-fill-able expectations are running rampant in today’s premarital counseling sessions.
Lastly to quote a wise wise man*
"We had common ground, it helped us stick together, I served SF my way, she served SF her way, her successes where mine and mine hers"
RIP Sir, you wisdom is truly missed...
