Husband doesn't want to announce...

So. I don't know if I'm just over reacting or if I have a legitimate reason to be upset... My husband has only told his mom and dad and maybe 2 friends that we are expecting. I've told my family and a few close friends. But after my 11/12 week scan, I really want to announce it to all of our friends and family on social media... And he doesn't want to. He says that he doesn't see why we need to tell everyone about it. It hurt my feelings because I'm really excited about this.. And he says he is to, but he doesn't really show me that he is...
