So my wife is continuing to lie to me should I call her out on it?

So years ago we were moving. She had this desk full of stuff and asked me to pack it. When packing it I found and read a ton of things from old love letters from ex's, a diary from years prior, a camera that contained a home video, etc. It caused lot of issues and fights. We have gotten over it. We'll last night we're watching TV and talking. She said something I know to be a lie. Because I read her old diary. She knows I read it we've fought and argued about it in the past. I shouldn't have read it she shouldn't have lied are the conclusions we came to. But she's still lying about things I know she knows I know the truth about. Should I let it go or call it out. I don't want to fight more. I just want us to be honest with each other.
