Sure.
It's very simple.
Men come from Mar.... more simple
one plausible part have been suggested, about a demographic gap ( didn't checked ). In fact Russia, ukrainia and bielorussia are on the top world wide countries in marriaying stats, but also in divorcing. The current stage of their modernity put women in insecurity, allowing them to divorce without the economic level to have them indeoendant and without having recycled the mariage institution in folklore or history, marrying is still a mn idealized value, which lead to a second hand mariage market and a foreign one. Such pressure on women have to be resolved by a idéalisation of commitment for men. Society van put such high pressure without means on women and both see them fully responsible of their life. Women are idealized as innocent and fragiles princesses.
I deserve a Nobel price for such great and heuristic theory !!
