I think that's a discussion you should be having with him - is there any possibility of doing LD while you're in school if he's really that concerned about finding a job, or maybe have him move as close as he can to Pullman but still have a good shot at finding a job? If he says he will move with you regardless of your choice, and you've both talked through the financial and career implications for him, you need to take him at his word. He's an adult capable of making his own decisions. You also do NOT have to make a decision for almost a full month and a half - give it a little time, let him research things a bit before you decide for him that he cannot possibly function there!
You'd also be surprised at what people can do from remote areas. Good friend of mine from high school is a dentist, and she received a job with the VA to work on underserved populations in North Dakota for 5 years in return for a moderate salary, her loans paid off at the end & relocation stipends on either end. Her husband is a patent lawyer - not exactly finding a whole lot of work while they're in the middle of rural ND! - and he is essentially working whatever remote gigs he can, along with raising their two daughters. There are ways this can work out for the best, if some foresight is put in.
AND, at the end of all this, you will have a more manageable debt load to be able to plan for your futures together. You guys may be able to buy a house or save for a wedding/kids earlier & with a lot more comfort than you would have with an extra $45k tacked on to your initial bill. (Remember, that's just the upfront cost, the interest over repayment will make that $45 jump up quite a bit more.) I'm always going to vote going for the cheaper option unless you have a significant support system near one school vs. another.
