Lain,
I know you have reiterated that it was ''Her'' that contacted you in the first instance, but in all likelihood it was the Agency/translator that was sending out the admiration letters on her behalf. Your lady not knowing anything about it until you replied...
Going back to the age thing, ..... These Chinese younger ladies can be quite fickle to say the least Lain, (especially when being an only child. But your saying she has a sibling sister, but then she is the youngest, so probably a little spoilt anyway....) Has she mentioned anything about the age difference to you??
The communication thing you have with her at the moment is rather basic to say the least. Not only that, it's open to abuse from the agency side of things. Which could be one reason why you get contradictory/conflicting messages. This is where the translator has written some of the replies, and these tend to be full of fluff to keep you keen ...lol!!! ( You'd be surprised how often that sort of thing goes on a these agencies)
As for not having a computer, that's pretty much a lame excuse these days. There are multitudes of internet cafes everywhere in China now Lain, even if she managed to find the time once a week to visit one of these internet cafe's, ...it would show some positive interest in you. And i can assure you when a Chinese lady IS interested, they tend to go that extra mile for you....
As i see it, your having a good few doubts about this lady at the moment, and it's going to be difficult for you to get to the bottom of anything, while your going through a third party all the time in your communications!! As your going over to China anyway in the very near future , why not leave things as a status quo and sort things out with her when you get over there. Believe me you'll know if there's a future for you both from ''Day One''
In the meantime, you can try making suggestions about other means of communication, in the form of emails, Phone calls, IM's and webcam IM's ...just depends on her English abilities, if she will prepared to partake in those activities. It can be a lot of fun, if your serious about each other, and at the very least shows willingness to at least try to communicate...
David....
