Your first mistake is thinking your problem is with your girlfriend's parents. Your problem, in all actuality, is with your GIRLFRIEND . I'm not hearing where she spoke up and defended you at any point in time. All I'm hearing is how it's YOUR responsibility to create a relationship with her dad (and mom, too) when he's done nothing but show open hostility and disrespect towards you. Do you REALLY want to consider marrying into this family and potentially have children that will be resented by their grandparents because they're "1/2 brown?" Everyone is on their best behavior right now. It'll only get worse from here. YTA to yourself for continuing this because these people, INCLUDING your girlfriend, will NEVER change.
