Spouse unwilling to relocate for a job promotion.?

My spouse is unwililng to even speak with me about relocating for a promotion. I work in a small town for a big company. I went to college and got my bachelor's and master's degrees. My boss says I do a great job, but unfortunately, there are no promotion opportunities for the foreseable future. My boss has advised me to apply for promotions in other offices throughout the country and is willing to give me a great recommendation. In fairness to my wife, we did move from CA to PA 3 years ago so that we could be closer to our families (my idea) and have a lower cost of living. My spouse does not work and takes care of the 2 kids, which is probably harder than my job. I'm just really bored with my entry level position and the work has gotten to easy. Am I being unreasonable? I'd like to get as many opinions as possible from any perspective.
