My bf doesn't want to tell anyone

so me and my boyfriend have been together for some time now. but honestly he hasn't told his family about me and only one of his friends knows of me and that's only cause they live together. his parents have come visit him at his place but every single time he is just like "oh i was gonna ask you to meet my parents but something happened" blah blah blah.. he is back home for the holidays and honestly i don't know if i want to be with someone that's afraid to show me off.

please give me some advice i think I'm going crazy
