Snooping was also feeding my negative thoughts of my wife and made me feel less confident about myself.
Also, this is the opposite for me. I keep asking myself (especially last night) "what is wrong with me?", "what did I do". But seeing the stuff on FB today made me feel MORE confident about myself.
I felt the same way. Once I found out my wife's behavior was VERY typical of someone having an affair, and then when my intel confirmed that she WAS having an affair, I knew I wasn't going crazy!
Just look up and learn about "gaslighting" -- it can have very serious consequences on the one that's being gaslighted.
I honestly don't know why anyone would NOT want to know the truth about something, so they can deal with it accordingly. If -- as Jack Nicholson famously said -- "you can't HANDLE the truth," then have a trusted third party handle it for you, and just keep you apprised of any immediate threats to you, your family or your finances.
