Re: Facebook is my enemy
Take it from me, you do not want to add to the trust issues by bypassing passwords. I found out about my wife's online affair by finding that she'd left Google logged in my acct on the desktop PC, and read her mail. We each considered this a betrayal on my part, even though it exposed one on her part too. Since then the trust between us was very strained, and I feel that I'm putting a great deal of my effort into demonstrating to her that I am trustworthy, as a tool to encourage her to open back up to me. Since discovering the online affair, we're spending a couple nights per week apart and she's moved her computer time to more remote parts of the house when I'm at home. She also blocked me from seeing her facebook posts/wall.
Then, a few nihgts ago, I woke in the middle of the night and couldn't get back to sleep. I headed down to the basement, and came upon my wife, on the couch in the darkened basement, chatting on Skype, presumably with the online boyfriend. This looked bad to each of us - it looked like she was hiding something terrible from me, and like I was spying on her. I was there for an embarrassing reason, found her accidentally, and had to come clean as a way to defuse a drop in trust. Going forward this is our first and biggest hurdle.
So yeah, take this into consideration before you break down another area of trust.
