My boyfriend's father introduced him to his girlfriend, but he didn't give me any answer, just saying what to do if he didn't want to face me.

Trust me! I don't know if it will hurt you. You've been together for four years, and he has this reaction to you. Maybe there are few emotional factors. He is afraid that he is not used to losing you. If he really loves someone, no matter how his family objects, he will resolutely "marry or marry" and fight with his family to the end, not to mention the photos of blind date and blind date! Make a decision as soon as possible! Let him marry you or blow!
