I have friends and some relatives in Italy, so when I visited them I saw lots of Italian women.
If we are talking about looks, well then obviously we're a bit different: you, ladies, have darker eyes/hair/skin, shorter legs/longer torso; and IMO are more temperamental.
In terms of personality women are different everywhere. So lumping them together based on ethnicity/nationality (be they Russian, American, Italian or German) leads you to nowhere.
I would be worried about what you're boyfriend is doing behind you're back if I where you. He sounds like a cheater. So be prepared.
Clearer skin, darker hair, darker eyes, chiselled features, and tough looking. But if I were with a guy who dug Russian girls, it wouldn't matter; what would matter is that he talked about them all the time instead of paying attention to the person right in front of him: me.
Ogni donna russa è un enigmi, ma enigmi sono tutti diversi.
E la cultura russa fa una donna una donna.
They Seem a little more Intelligent, than American Girls... -But maybe THAT's because They don't have as much of a "Choice..." ;)
