Although I am not married my significant other (7 years) finished his residency as I was applying for first year....I can offer a couple of things of advice:
-many times I was asked how I was going to handle medical school (and going back to classes) particularly being older, and I would reply with a)my boyfriend has been through school and residency, I am completely aware of the long hours and energy that school takes b)as well as he will serve as an excellent support system because he is also aware of the amount of time and work
-I also used him when they would ask to me the dreaded "where do we rank on your list question" so we were both looking in boston, ny and dc and I would say that he is looking for a job in NY and that going to school x would really work out well for both of us.
-When he got a job in boston (which he will start in a year

) I had to stop saying that and then actually defend why I would go to a school away from him, but I would comment on how he is going to be busy and I will be busy and that I want to go to a school where I would feel comfortable...
overall though after seeing him go through everything you have so much insight into the process. If you haven't already applied I would recommend going (with your spouse) and talking directly with the admissions director...everytime you can get your name across their desk in a positive way will help you in the end....Good luck!
