I'm offended at my wife of now 27 years
Why would you be  offended at your wife?
She tells outrageous stories to people.
It is ok to disagree with her. It is good to be honest and work through your problems and not let them simmer till you explode.
She said she was sleeping with a coworker for quite a bit before we were together and I'm mad she did it in my house.
I see how that could be unacceptable, but if you weren't together yet then it's her history and that is all.
