Have been reading your posts. I am a newbie, still reeling with emotions. The big difference with my sitc and yours is that my W had A. If you knew us and her, you would say that would never happen. A good friend of mine said that many W's are not running away from something, but to something. With that being said, it sounds like you have done you due diligence and checked and found nothing. That is good news.
Like you, sometimes when we talk, it seems like nothing is going on, you wouldn't even know that we were in this sitc! The happy attitidue is such a blessing, isn't it.
It sounds like you are making great progress and taking the steps slowly. I have zero patience, but it sounds like you are DBing so well. I am working on the first two steps still, reducing the negative emotions and good energy in the house. It sounds like you are on step three - friendship. I hope so, success stories is what we all need to hear.
Peace,
CBK
