Need Advise bout my friends ASAP

So I live in Wisconsin, USA and in WI you can ccap someone which means you can look them up through the court house and look through their public records. Everything will be found including criminal records.

My father is abusive mentally and physically and hasn’t really been there for any of his kids. Sometimes when I’m upset I’ll cal my friends and talk to her and explain how I don’t have a good relationship with him. I never tell her about what he’s done. My dad has a record and desperately don’t want anyone to know about it so I basically never talk about the shit he’s done. My closest friends don’t know.

Well today as I was leaving school my best friend came up to me and told me she ccapped him. She said she found all his records and then just left. I’m upset and really dont think that my family business is any of her business and that she should have never done that. Am I being reasonable or dramatic? How do I react?! Please help!
