Would you be mad?

I kept my pregnancy a secret from my coworkers because they all talk to much. So I planned to keep it a secret from them until all of my family had been informed. So one girl found out by a close friend slipping and made a comment about me not being able to go out for drinks.

So this other gal practically texts and blasts on social media my pregnancy. When I confront her she says “I didn’t know it was a secret”.

Now I know my hormones are a bit crazy, but I want to throat punch this chick. Am I wrong for being upset?
