She does kinda keep her messages short tho, i have addressed this and she says that she is not too good at expressing herself and is a little conservative. I see this as a good answer
Andrew, for months all I received was short and reserved letters. It seemed to me she was so cold about me and the relationship. I used to think that there was something wrong with the relationship. But when I visited her in January, she was really affectionate and kind. She was a wonderful person, nothing like her letters.
I had a bit of a fuss along the way, but that's another story.
I think you need to keep reminding yourself that there's a really big cultural gap between you and the woman you are writing to. What she writes in her letters doesn't "mean" the same thing to you, as it does to her. If I have learned anything, it's to give people the benefit of the doubt. Just because the letters are translated doesn't mean that the cultural gap is any less than it was in the first place.
In my humble opinion, I don't think that the letters necessarily give you a perfect indication about what is happening in the relationship.
My feeling about writing for all this time, is that is you write regularly, back and forth, and mix it up with some other way of communicating (eg over the phone, internet or webcam), and you're having a good time, I think settle back and enjoy it, just go with the flow.
Of course, if you are not enjoying it, then it's best to end it early and move on to someone else.
