pregnancy secret

Brittany
So I am 17 weeks and I have told everyone close to me and some people at work about my pregnancy but mychild's father has not told one person. When I ask him why or when is he going to tell people he doesn't really give me a clear answer. I know for a fact he knows is his child, we talk about the baby daily! And he has been to every single doctors appointment. And it just pisses me off because I don't understand what's the secret and your reasoning for not telling people. Like I'm honestly fed up at this point. Am I overreacting if not how should I handle this?
