Given the million young men who have fled Russia to avoid this war, and the hundred+ thousand already killed by Putin’s war, I suspect Russia has even more young women on these marriage sites than does Ukraine. I know one US man who married one of these Russian women thirty years ago. So far as I know they stayed married and had a child.
If they make it to the US, they will be happy to see that our inflation here is much lower than in Europe and probably even lower than in Russia for most foods and common luxuries like cigarettes and wine.
There's a wealthy Russian-Ukrainian couple who (unfortunately) bought property in my town in Sicily years ago. She'd sport black eyes and bruises constantly because he was pissed that she was constantly cheating on her. A real shitshow. Everyone here hates them and their boorish, low class behavior. Research my comments for the whole, sordid story, a common Eastern European "love" story based on my experiences with those people.
