Keeping it a secret?

I don’t feel like my baby’s father is going to tell his family or his mother at least that he is expecting a child. I’m in my second trimester and still nothing. I sometimes just want to tell his mother myself. I already told my parents at 7 weeks.

At work my coworkers keep telling me if I or him were their kids and I didn’t tell them any sooner they’d feel hurt that we had been hiding it for so long.

Do I not have a say to tell his mother? I know for a fact he won’t tell her with me around. I don’t know what to do. I hate having this as a secret.
