What "business trip" lasts four years? I know members of the military may go away for one year or so, either to a foreign duty station or war in recent years, but four years? In this case, I'd have to ask the husband is any job worth having to leave four years from his wife for? That's not a business trip, that's a permanent move situation where the wife would go... There's not enough details here, something is definitely missing.
