My wife is going to move to wherever I get in but we are facing the prospect of a prolonged period of long distance. When she did her masters - prior to us being married - we did a year and a half long distance. She then got a job in our current location and we both moved out here. As I had returned to school at this point, I finished my UG out here and it has worked out well for her career and my education.
But now, we're at a point where if I want to continue on this path I need to go to a place with schools that will have programs for me. She's been incredibly supportive through this whole process and I have tried to limit my selection of schools to places where I could see us living for 5+ years and she would have ample room for professional growth. So far its worked out well but of course it all depends on where we end up and what the job market there is like. Its a tough process, but I am fortunate to have an incredibly supportive spouse and as we make the decisions together I'm confident that we'll end up in a good situation.
Oh, we currently both commute 45mins - 1 hour in different directions. We live in a city in between our two places of work (I work at the school I just graduated from so its been like this the entire time) so I feel that has prepared us a bit in case we move somewhere where we once again have to find a place to live in the middle.
