Why does my gf always have to win the argument. Even when I prove she’s wrong she’ll never admit it. I don’t get it.
You have a preview of what your relationship will look like down the road. If your relationship is to continue, you both should see a professional to help you. Either she does not recognize what she is doing, or she recognizes it but doesn’t give a damn. Neither is a good sign. When people start keeping score in a relationship, there are no winners.
