OK, an update here. I wrote my lady a very frank letter telling her what I expected from our communication and what I have missed so far. I was a bit concerned she might think I was too frank, to be honest. But I had no choice but to tell her my true thoughts. It turned out it was just what was needed. We've had a really good discussion and it seems that she understands that I am not questioning her sincerety, I am just looking for some kind of security before visiting her.
She has explained that the wedding thing is not in our planning anymore and also apologized for all the confusion. And most importantly, she finally gave me all her contact info. Her QQ number, her home address (I only had the address to the company she works for) and phone number. Now we're doing what we should have done months ago: writing text messages in pinyin. It seems she has been very shy to talk because of her poor English. Maybe my recorded message for her did the trick as it showed her that I do speak some Chinese and she can understand my poor putonghua.
Last weekend I was seriously contemplating to pull the plug and save my money for something else next year. Now we're back on track again and I can focus on my Chinese exam next week. :icon_cool: Of course there will be doubts, I'm sure from both of us, in the future but now I feel I have got what I need to make the step and visit my lady in China.
Unless something happens very suddenly once again, I will be making my trip to Zhanjiang on December 27 according to plan. I want to thank you all for your thoughts here. It has been invaluable for me during moments of doubt and insecurity to read your advice and be able to cool down. Thank you all!
