Right there with you buddy. It hurt bad when I found out about my "sweet and innocent" W.
Forget about what everyone is telling you about forgiving her. You'll get to that point when you get to it. You're going to do alot of soul searching between now and then. Just concentrate on how you're going to be when you actually "see" her again. If you're lucky you'll throw up on her.
I would actually cancel seeing her. Maybe if you could say you're sick and can't make it. Which in this case you are...sick of her! LOL
Your son will be hurt, but you have to be mentally ready first.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
