I did not understand all of what you wrote, but it seems you created something in this story.

I'll explain very simply. I completely fell in love with this woman from the start, and at the beginning it was magical. If you ever experience this sometime in your life, you'll understand. You cease to function, your thoughts and ideas concentrate on just one thing - how to please my partner, how to make her happy, and this is what you do. You start to abide to wishes, you forget to compromise and when the first few things start to happen, you simply glance over them.
What i did was to completely devote everything i had to her. Yes, i helped her financially, but i am far from rich, actually, i'll be what you consider below average, but i did what i possibly could to make her comfortable - both emotionally, and financially, because this is who i am.
Her language skills are more than enough, almost excellent, and everyone here in Norway speaks English basically everywhere, so communications isn't the problem.
You may believe that i am jealous which i am really not. If you love someone, set them free.
I simply asked if her behavior is normal, but i start to understand that this is perhaps more culturally related than i could anticipate. I understand this now, and it explains more than i could also anticipate. Russians are simply more jealous than Norwegians, and it explains a little of what she told me where it's completely normal to have relationships here and there, carnal ones which i simply didn't believe was so widespread, but i understand that there are embers glowing.  

For my own sake, this thread can die as i have received the answers that i wanted. We had a cultural clash, and we were perhaps extreme in both our ways - i am too open, she is too closed, and the result was disaster. Its good to know though because emotionally i moved on a long time ago, and this gave me the final closure.
14 days left and my foreign escapades are finished
