She grew up in Ukraine. Suffice to say the primary difference I've noticed is that she has an extremely clear and firm belief on what constitutes as Man shit and Woman shit. Thus, anything that falls into my category she fully expects me to do 100% and any expectation that she should help is patently absurd and pisses her off. This is actually quite beneficial most of the time because she doesn't bother asking questions about Man Shit and has zero problem cleaning up, laundry, repairing clothes, and whatever else. Although I never minded doing it myself.
A nice change from dealing with American women and what I refer to as Disney Princess syndrome. Where everything becomes an argument as the expectation is that you just do what she wants. Got real tired of that shit after awhile. Many women seem to suffer from it.
As far as finances we keep them separate. I manage all bills, and investments and she just saves as much cash as possible as there are a number of major purchases in Ukraine she wants to make next year that all require cash only. Like a flat, and some other things. After that I'll be getting her on my investment to cash ratio... or trying to. But cash is king where she grew up and it will probably be hard to shake that off her.
