I think Socrates said "An ignorant man thinks he knows it all, a wise man knows that he will never know it all". Those are very powerful words when you think about. How many times in your life have thought that you knew exactly what was going on...and then found out otherwise? The only true thing you can know 100% is yourself!
Sharing the faxes and emails was very bad in my mind. First, the counselor already shared them with her. So the cat is out of the bag. The second thing is going to be your wife's reaction to them. I had a blog online and a journal that I let my wife read (regretfully). So in these documents I expressed what I had learned about myself (good and bad), thoughts on my wife and marriage, and what I thought was causing our problems. The reply I got back from my wife was that I was looking for a pity party from everyone else when nobody really understood her side of things. Just an example of how an MLC'er twist things to themselves. Here I was, just like you, acknowledging my shortcomings and my wife only thought it was a pity party and not the powerful insight into myself that is actually was. I have since learned that what she thinks can't really affect me and that I have to let it roll off. In my case, just last night, my wife got pissed at me for letting the kids play on the computer while eating bananas, but would never mention how I took the kids to there soccer games, made breakfast, lunch, and dinner for everyone, got homework done, got the kids bathed, got the groceries done, etc.....but you have to let there comments roll off. There are in the world of "me" and see nothing else beyond that.
