We live in the US but our son who, who has lived in Sweden for the last 30 + years has tried to talk us into moving to an apartment over his garage. I love Sweden but I just wouldn't be happy living out of the U.S. I am a visitor when I go there and I'm sure that's always how I would feel.
I felt like a foreigner when I moved to the UK for many months even though I loved living here. But it's felt like home for many years. Been here 15 in April.
