You must be ready and prepared to visit her at some point in the future.
It has been my observation (by watching and talking with both western men and ukranian women) that a woman will generally give you about 6 months to decide you will visit.
Writing/dating only one woman at a time is a bad idea.
If it doesn't work out with her, than you are back at ground zero and have nothing. Not to mention the time that you have wasted, and the money if you actually took a trip to meet her in person.
Make her wait longer than this and she will think you are not serious and probably move on to someone she thinks is!For most men, I would say that even if they tried it would not be possible to control a Russian or Ukrainian woman anywayshe is strong-willed and fiercely independent. Not asking her questions: You are looking for a wife, not someone to just pass the time.Well, then again Seriously, these are serious and honest women (for the most part) and they deserve the same respect.An honest woman would not ask; she has too much pride.Besides, she has already lived for 20 years without your "help." Why does she need you now?
Show them your sensitive side, what you like to do, how you think and feel. Thinking she is just after a visa: Then again if you thought this way, would you really be interested in writing her in the first place?
