Introvert married an over the top extrovert

I’m a private person, I don’t go around telling people my personal business. My husband knows this but he still goes around telling the entire world from people he works with who I’ve never met to Chinese food store workers and the NEW diner that just opened, he told the manager MY business! He NEVER was like this before we got married, if he was I would’ve left him! I fight with him all the time about this. Now I have to keep secrets from my own husband because of his big mouth.
