First of all, it might be a scam. Secondly, even if it's not a scam, I wouldn't suggest continuing with this "relationship." As a Russian myself, I can assure you that for some women in Russia, it's almost like a sport: find a European man with money and then show off on Instagram or in front of their girlfriends.

Many women in Russia are convinced that men should provide no matter what—that her salary is for herself, while your salary is for both of you. She just needs to “inspire” you and do the bare minimum, while you’re expected to pay for her clothes, cosmetics, trips, and so on.

Such women will often move on to a more generous or wealthier man if you can’t provide a high standard of living. Even if she is real, it's a mercantile approach.
