And I don't agree with if she loved you she would be there or this and that. That is for the old timers, times are changing and I sure she wants to have a position in place to be financially ok if the relationship should fail. I am sure she is thinking to herself, "what if I really hate it there." I figure she is teaching right now and has to at least finish up the rest of the year.
Plus you want her to find a position first. She will be in a new area, without a job just sitting there waiting for you to get home from work. Maybe she feels that she will get bored without work. She will not feel easy about this and you are going to be the person to entertain and talk about your day as she will have nothing she will want to talk about. Just saying that I bet she is stressed by the situation.
