This is an interesting question to debate ....

I think that Russians are among the most conservative Europeans in this matter, together perhaps with French and Italians and a few others.

Whether this is a good or bad thing is down to personal preference, I guess - and there are surely exceptions to every rule!

If the guy happens to be very short of money, and the girl is not... then it makes a lot more sense to go "dutch"!

But it would be a bit of a romance killer, I think!
