Haven’t met my boyfriend’s family members, should I be worried?

So I’ve been with my bf 2yrs, we are great together, he’s met my parents and most of my family and friends. He’s introduced me to his friends and that’s it..at this point I feel I deserve to meet at least one family member, I’m starting to feel like our relationship is a secret or just a phase and it’s not going anywhere. I’ve brought it up a few times and he always has an excuse like they’re not around or he doesn’t know when he’ll see them or something..I don’t want to keep asking him because if he really wanted me to meet his family members he’d ask...am I over thinking things? Should I end this before it’s too late?
