My boyfriend won't let me announce pregnancy. .I'm 16 weeks!!!

I'm really excited now that I'm growing and felt my first flutters, but my so says do not tell anyone. I can't post it on Facebook either! Now I joked around and told him I made a fb post announcing my pregnancy and he flipped! ! I just wanted to see his reaction but he's making my pregnancy lonely and miserable. My own family doesn't even know. I'm 16 weeks I don't know how much longer I can wait.
