Try to imagine a Russian woman being near you every day for many years - with her character, appearance, voice, manners etc. If something irritates you - do not pull correspondence because you don't need a bride who irritates you even in your imagination. So, it is better not to give her a hope and write the "finishing" mail in soft style instead of cutting the correspondence sharply.
If she categorically tells you "no" - do not be offended because not only you, but she also has the right to choose her would-be husband. In this case you can act differently. You can stop everything to remain single for some time. You can't order her (for example, by mail order brides service) but if you get used to be a leader and want her to be with you try again and again to win her heart. If you are not sure about anything act as your heart prompts. If you are not a leader and want to have the woman at the same time then everything depends on circumstances (but most likely - she won't become your future bride and you will have to wait the for an initiative woman). Be ready to pay her expenses: her tickets, visas, hotel etc. If you are not ready to do it - you have very few chances to meet with her. Have a couple of sample letters - with questions and the story about yourself. It is not necessary to have more than two patterns (it frightens off others) because as soon as you have understood that the lady does for you, you should write her individually. Be able to write peculiar mails with some sense of humor. It is better to think whether it is worth starting to correspond with the lady who is in bathing suits, incredibly painted make-up, with very big décolleté on her photo. She demonstrates her photo to the whole world. Do you think that such a lady can become your future bride? Are you sure that she will be with you when you are 50 and she is 27 and there are a lot of young men around you. To tell the truth, here I shall notice, that the age is more individual question (here many factors should be combined).
