I don't know what to think

I've been with my bf for almost 9 months. He already knows my family, but I don't know his! not even his mother, he never took me to his house, I just accompanied him with my dad, but it was late so we didn't got in. I don't know what to think, I feel like his hiding me from them, he told they know about me, he talks to me about his brothers and his mother, but why didn't they tell him to bring me to their house to get to know me? I think he's not being honest with me.
