One thing to remember is that nobody gets everything in life. One can either be satisfied with what they have or hunt for greener pastures which may turn out to be a mirage. In the process, one loses out on what they had earlier. I personally feel that you have a great compatible partner and should not desert her just for better prospects. Rather it would pay to explore if such minor differences and mutual expectations could be ironed out for mutual happiness and satisfaction. Remember, each one of us is different and unique and lovable for this very reason. And opposites do attract!
