First of all, there's a lot of non-Russian women, from Ukraine, but also from Belarus, Kazakhstan.
Secondly, Russian/East European (not Central European, like Polish, Czech, Slovak, etc)women have "natural mental strenght". It is because Russian/Ukrainian/etc society is much more Asian, than European in many ways. Role of woman is much more traditional, than in rest of Europe. Men are treating women not so well, in the past badly, to be frank. In the same time, under the Soviet Union, woman was treated in special way.
So, Russian, Ukrainian, Belarussian, Kazakh women should be strong, mentally, to live on their own. And they are not under influence of Western, feminist, ideology, so, they stay in their traditional, feminine role.
That's why they are so special.
