There's a comment below this one that is flagged and dead, but honestly it sounds exactly in line with what I heard from a guy who lived in Korea for 12 years, eventually getting married and starting a family. Those were basically his exact reasons for moving away, that and wanting to be able to afford a house with a yard for his kids: Difficulty renting, difficulty with banking, language barriers (he was very self-aware that this was on him for not learning the native language, but still a factor).
