Hello, Janne! Thanks for the compliments you've done to all women here!
I completely agree with you that loneliness is not a funny thing, that's why people are here. You answered yourself to your question - "What can a simple divorced western man like me offer a russian beauty...? - I am fair, honest, faithful and not drinking." Perfect!!!
You've got a lot of doubts about women here and it's natural. You "want to be sure that YOU are the reason, when a woman is going to leave her home (family-friends-work). I can't understand what can be the other reason (?). If she has everything for life here, what can be the other reason to leave?
You want to be absolutely sure that 'this time is for the rest of your life'. Well, one man from here (a divorced one), who lived in a devastating marriage for more than 15 years, told me: " It's impossible to live alone. Woman is a locomotive engine and man is a train. She encourages man for moving, doing things, creating, changing, going ahead." But I want to tell you that nobody in your life can give you guarantees that this 'locomotive engine' won't lead you into a dead end in the dark tunnel.
Well, be positive, quiet, confident and persistent when the time comes. Everything is only in your hands!!! Don't believe that Russian/Ukrainian men are 'rare monsters'!!! And don't mix two notions 'to leave' and 'to travel'.
