My relationship

My bf and I have been dating for almost 4 years now we live an hr away from each other but visit each other often.

He’s met my family and spent time with them and yet I haven’t met his family. Not once. even when I do go out to visit him we enjoy your time together and it doesn’t bother me as much however when I’m thinking to myself that’s when it hits me.

I talk to him about it and eevrytime he will say it’s because his family is different and he’s never been with anyone else outside of his race and religion.

However I don’t know if he’s telling the truth or not
