I think you missed the issue here. She hasn't turned to the internet for anything. What I am talking about is that I invaded her privacy by looking at her history. I didn't find anything .. she emailed her ex more than I thought, but she's been willing to share the messages with me and I know that there is nothing to them.
My problem is should I continue to keep the secret that I invaded her privacy more than once, and that I looked her up on the internet which she explicitly asked me not to do.
Throughout none of this, I have found nothing incriminating. I didn't expect to. It was just my way of venting my anger.
