You know the what the real causes of failure in your earlier relationships were.
And some, perhaps even most, of the blame for those failures was yours. Be honest with yourself and try to grow as a person.
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.
Remember, foreign girls are signing up with Global dating agencies, because they are not happy with their marriage prospects in their home country, not simply to make you happy.
Regardless of where a foreign lady grew up, it takes confidence and intelligence for a woman to turn away from men in her own country and decide instead try to marry a man from another part of the world.
