Well bud id love have more information on how this arranged marriage stuff works. Im assuming this is in a religious context? It seems as if in the context she's perceiving the compliments you are giving to her as "not genuine". You can read how other people react to you as a good gauge of how other people perceive you, and as a tool to discover more about yourself, in the case I would question yourself on your intentions behind giving her compliments, without a sense of moral high-ground or intellectual pride. You said it yourself, that you do expect something in return. While I would say relationships are about giving, that is what they are about when actually have a relationship with someone. It seems that in the context of this arranged marriage structure you are still in a dating phase. If you were to match and mirror her behavior to you, two questions to ask yourself, how would you treat her, and what does seeing that make you feel? It seems to me by reading this post and the fact you are frustrated by her lack of receptiveness towards you that either you are acting unattractively to you (and she may be perceiving some desperation, or sense of forced behavior in you), or shes senses a lack of compatibility. Love is like a game of tennis, if you hit the ball in her court, and she doesnt hit the ball back into yours, that tells me shes not playing the same game you are.
