True love does not conquer all...
Waiting until you complete probation at your career destination might be the best solution...that way the schedule and geographic options are known quantities going in, and should only improve over time.
Of course not everyone can wait that long. This may seem a little calculating, but you want be careful about who you bring along for the ride...otherwise you can harm that person, as well as yourself, your finances, and any kids involved.
The ideal aviation spouse would have marketable job skills in a field which is very portable and allows flexible works hours. She/he would also be very adventuresome and independent, and easily able to make new friends in strange places. Doctors, nurses, webpage designers, etc.
Flight attendants are usually a poor bet, you have scheduling issues that make it hard for her to work after kids. Also most pilots have a different philosophical outlook than most FA's...if you must marry flight crew, find another pilot.
You do not want the type who is overly focused on bling, hollywood, money, and appearances. Her romantic image of airline life will not hold up well to reality, and when she bails she will want a monthly consolation prize for her efforts

Having financial goals is OK, as long as she has patience and a realistic understanding of the road ahead.
My SO has all the good attributes except that she is not as portable as I'd like, which limits my career options geographically.
