croatian (and other balkan/eastern euro girls in general) come from a society where there's little feminism, and men are the dominant ones. you can get away being afc with a north american girl sometimes, with girls from the balkans, your game has to be top notch.
also it's weak but, they pay attention to what you wear, where you work, what car you drive, etc. most of them tend to be somewhat golddiggers and expect the guy to take care of them and sh!t.
good luck.
