Nez,
In my experience, this is common. After all, you are both supposedly looking for someone to spend your life with. During the two years that I was looking for a mate, I had similar conversations with 3 women. All were very open and promising. The first found a love in China. The second, I doubted our compatibility. The third, I thought was the love of my life.
The agency (ChinaLove) in Shenyang set up a QQ video call in their office. We talked for an hour. Everything appeared on the up and up. We continued to send emails through the agency for several months. She continued to encourage me with talk of marriage and our happy life together. I cultivated a relationship with the translator by sending notes at the end of our emails. This proved invaluable.
I went to Shenyang for 3 weeks. After 1 day with the “love of my life” it was apparent that it was not going to work. No how, no way. I was devastated, and I was alone in China for 3 weeks. I went to the agency and the translator walked me through their portfolio of women. She was very forthcoming about; “She looks nothing like her picture. You could never have enough money for this one.” She led me to a woman that she said, “only wants her happiness.” Based on her knowledge of the two of us, we planned a meeting the next day. Frankly, I thought that at least I had someone to spend time with. Long story short, we spent the next 3 weeks together and loved every minute of it. I returned 6 months later, for 3 weeks, and we were married.
I am not trying to throw water on your fire. I am saying, expect the unexpected. There is nothing to compare to, or prepare you for that first face to face meeting. I don’t know how the site works that you are using, but the translator at the Shenyang ChinaLove agency was highly instrumental in our success. Today, the translator and I still send letters to our private emails and discuss life. She has become a good friend of my wife. From what I read here, this is uncommon, but I think it is worth mentioning.
