There was a similar thread started a few months ago:
Military Spouses, Parents and Families. I take it from that thread that there are others arounde GC in similar places in life, although that thread is only a page or two long.
There's also this thread that might have some interesting insights:
Would you marry someone in the military? (I haven't read through it, though, so I'm just guessing.)
I don't mean this as a "do a search" post -- just thought these previous threads might have something of value to your question.
Good luck to you and your boyfriend!
