There is no TRUE LOVE ("unconditional love"). Only some girls like to fantacize about those silly love stories. But this does not mean you cannot find a beautiful and honest girl in China who loves you and wants to spend her life with you. I am not sure if it's because the girls you like to approach fall into the category you just described. For the sake of an example (nothing offensive, take it as a joke), Bo er said a couple of times that in Australia there are no virgins of 16+ years old (or something like that). I have not been to Australia, but if we assume the situation in USA is somewhat similar to that in Australia, then I'd think it's because the girls Bo er knew fell into the category she had described -- because I think there are a lot of virgin girls of 16+ years old in the USA. If depends on who you know or you like to know.
Maybe you need to adjust your expectations and approaches. I believe there are tons of good girls in China, still.
