Whether this single woman can obtain a visitor's visa will depend upon her ties to Russia and her intent to return. It will likely be very difficult for her to obtain a visitor's visa unless she has strong ties to Russia. She can always apply.
A visitor visa is not to be used to circumvent the is country's immigration laws. If you think this relationship is leading to marriage then it may be best for you to travel to Russia to meet her. You could also choose to meet in a third country to which she can obtain a visa. After you have met, you could pursue a fiancé visa for her.
