Peter, I've never commented on your thread but have kept up with it. My strong advice to you is to speak with a DB counselor or your own therapist before deciding to expose the affair. While many of us on this board have been in your shoes & certainly want the best for you, none of us posters are experts. I am very fortunate to be in piecing/reconciling, but it's only after making MANY mistakes with regard to my husband's affair. Absolutely detachment is key, but right now I'm sure you are still in shock, so don't expect too much of yourself right now. That shock will be followed by some intense sadness and anger. If you have any hope in your heart and mind to save your marriage, PLEASE seek professional help with this matter. How you handle things can make or break your situation. I wish the very best for you, and I hope despite the nightmare you are going through, you and your girls can have a fun Halloween weekend together. They deserve happiness and so do you.
