My wife is American, she came to study in Sweden, I'm a native. She lived in Sweden for 7 years and was struggling to learn the language, people are very insistent on speaking English if they hear that's your native language. That's nice and all, but it makes it hard to fully become part of society. The biggest issue is the individualism bordering on egotism, people just don't want to deal with strangers.

Being half-Spanish I often compare to that culture. Over there you'll see kids, teenagers, adults and old people hanging out in bars together at 1am on the weekends. Over in Sweden you're supposed to stay locked up in your apartment after 6pm once you're past your 70s.

If you're seriously considering moving away from the US I'd suggest looking at Norway, which seems like a much friendlier place to me.
