Lucky that my wife is in China for 2 weeks "family reunion"...thus I am Bacheloring again and bored to tears...so I can happily spend a few moments responding to your bombshells!!!
MMMMM....about babies......I went through this saga for nearly 6 months. I am possibly the oldest member here....me or Willy would be in a close race for that honour ...and my wife was continually prompting me to consider a child...that was BEFORE we were married. Once we actually got married and she came to Aus, she reluctantly 'fessed up that she did not really want another child (she is 45 by the way) but she was told that she MUST be prepared to have a child with her new Western Man...he will demand it !!!!...so, maybe your Lady is going through the "unrealistic expectations" when she mentions another child...maybe it will all go away once she is sure of you and has a wedding ring on her finger.
If not...well, its really up to you...and the best of luck. For me, at my age I cant think of anything worse than another baby..........even though its still fun to keep trying !!!!!!!!!!!!!!!!!!!!!!!(better living through modern Chemistry)
As for lack of shared everyday stuff, I have never experienced this, from day one, Ming was keen to share everything about her life, past, present and future. Sometimes I was glassy eyed with all the trivia, but I put on a brave face and humm'd and haaa'd in the right places.......still do.
I guess we all get to know some differences in Chinese Women along this track...vive la difference...as they say !!!
