Haven’t met his family yet

I’ve been with my boyfriend for 1yr 7months now. I’ve yet to be introduced to anyone in his family. We don’t even go to his place cause he says theres to many people. He lives in his mother’s house with one sister and her two teenage sons and her boyfriend. He has another sister who lives there as well in a separate part of the home with her boyfriend and two kids. We always come to my home and it’s never a option of going to his cause he says there’s to many people and his room is small. It really bothered me and I brought it up to him and I was really upset he said im over thinking it . He has four sisters and his mom I would love to meet. One of his sisters is pregnant and my boyfriend and her boyfriend are really close, I would love to get to know her. He told me that his brother in law wants to meet me and I’ve spoken to his uncle and to his cousin once before. Do you think I should just let it happen when it happens and not make it a big deal?
