1) travel/living in a foreign country, is always educational.
BUT.... it also DEPENDS largely... upon IF an individual, can "acculturate" to that given country/people/culture.
If you cannot, then it will not be a nice time.
2) Speaking a foreign language, does not automatically mean... that the experience will be either good or bad. Because... the bottom line is: IF a person can ACCULTURATE... within... that given country/culture.
It requires, an ability, to do so. It is not just about being able to speak another language.
3) While in another country, you have to be able to flex a lot... in perceptions. And being able to, learn/experience that culture in its entirety.
4) If this is a Military type organization that your Husband will be employed with... then you will be in that microcosm.... of an environment and organizational "culture." So you would have to get used to that too.
In addition to, experiencing the overall country and its culture.
If this is a Corporation that your Husband will be a part of, then you will have that corporate "culture" to adjust to, too... but you will also hopefully get to know fellow ex-patriots, (Americans) that can help you all adjust.
I am an Anthropology Major, and have done field work etc. And I have lived in and been to foreign countries. I tend to immerse myself, in any given culture. The people who cannot adjust or have a hard time adjusting to other CULTURES or to another country... is mainly because they cannot acculturate, or do not want to.
It is a choice... but also a willingness. Or not.
That is the "advice" I can give you, per my own experience and training.
My Husband is from Europe. I am an American.
We speak those languages.
But speaking a language... versus being WITHIN that culture itself... are 2 very different things.
Both cultures, are VASTLY DIFFERENT... and in terms of how they raise children and teach them and in their academic atmosphere.
If you do move, I advise to get some cultural books, and learn about that country/its people/its ethos.
