Your needs are not wrong. You need love to be shown you need her to smile but expecting them from someone who has clearly shown she cannot meet your needs the way you want her to, will cause only heartache.

She is speaking french, you are speaking German. Unless one of you is willing to change the language then you will never understand each other. You expect her to learn your language but she has already learned as much as she is willing. Either you accept what she has to offer and you both learn this new language together or you find someone who can offer what you need.
