First of all, it is somewhat credible that at 25 she has had no prior boyfriend. Space is at a premium in China and there just aren't many places for privacy unless you have real money, which most Chinese do not. Chinese women mature more slowly than western women, so that has a bearing as well.
The definition of infatuation is projecting on someone else your own hopes, dreams, values; they become a perfect reflection of what a person is looking for. So yes, she could very well be infatuated.
Now what you do with those two pieces of opinion is your business. *grin*
