Am I wrong?

Am I wrong to be angry at my fiancé for telling a all of his friends about our personal and private issues? Now their girlfriends know AND my staff in my business.

I am an extremely private person and he knows this. I feel so embarrassed that all of our friends are discussing our personal problems. It makes me not want to be around them and feel awkward.

Our issues surrounded having more children, leading to arguments about even staying together and now they all know absolutely everything we’ve spoken about.

He doesn’t get why I am so infuriated. Am I wrong?
