Yes, there are Russian ladies who have never been online and Chinese girls whose family raised her to honor and always obey her husband.
However, today those foreign girls still probably know who Brad Pitt is and have some idea of current fashion and even more important know that women in the US and the European Union lead vastly different lives than they live.
And some, perhaps even most, of the blame for those failures was yours. Be honest with yourself and try to grow as a person.
If do not recognize your own weaknesses and try to correct them then you are just asking for a world of hurt and humiliation.
If you are thinking about persuing foreign girls for marriage there are several issues that you should consider.
The first of course is what area of the world you are considering pursing a bride from?
Not that older women do not have many charms, but the pursuit of younger women by older men is prevelant in every major cultural group around the world.
You really have to track very far off the beaten path to find foreign girls who are not a part of the broader world culture on some level.
There are cultural differences between say Eastern European lady and an Asian woman, but you should avoid falling into the trap of stereotyping foreign brides, because this can fatally poison your relationship before it ever starts.
The foreign women who sign up for international dating agencies are individuals and you should never forget that fact.
You can find a Russian woman who is totally submissive and there are Filipina's who are pushy type A women.
Whatever grain of truth existed in the national stereotypes has changed, because the countries where most of the mail order brides today come from have under gone enormous social, political, and economic change in the last twenty-five years.
