As you said you are a Doctor, your wife's lamentation that your career is more important than her may have some aura of truth to it. There are all kinds of specialties in most cities in all States. That you pursued something niche enough to dictate your life in such a manner on where to specifically train/work/life surely is noteworthy on that point at least a little bit I should think. Luckily next year will apparently bring things around hopefully as you say.

Charlotte is unable to work

When my father moved us for his promotion it really was rough on my mother. She went from working a part-time job she enjoyed, friends, family to being alone, no job no friends living in the countryside in a beautiful home wanting for nothing (prison) while he, like you, worked all day. Your wife is in hell and I sympathize. At least she isn't also dealing with raising children.

Why must she be with you if your situation is only for 1 year and you are moving back near family anyway? Why not let her go back to reality, maybe find a job and set up camp for your coming down the line?
