I am in the same place as you. Going on 15 months since the bomb and 2 months since I confronted her about her EA. I have no clue what she has in mind for us or her.
My only comfort is that I am keeping the family together for the benefit of the kids. There is no way that I will put them through the trauma of Divorce if I can help it. It [censored] and is painful, but it is a sacrifice that I am prepared to make. Based on what I have read, I have at least another 8 months of this while my wife leaves the fog of her EA.
I feel your pain and share your frustration. I don't see any progress but at least we are together and I can continue to show her that I am no longer that person she grew to dislike. Hang in there.
