One thing I would say is follow what's inside. I assume the reason you are here on the board is that you would like to have the chance to save your marriage. Let that be your guide. I also think people close to you will want to shield you from hurt.
I know how tough this is on you. You are in the place where you are the one who has to place themselves in harm's way. I did have a feeling what your first thought would be. I would never criticize that thought.
