I absolutely agree with this "They have to heal from the betrayal first, or at least openly begin the process.", especially in light of what Chrome's wife has said to him.
Chrome, what have you two done...in order to deal with the A? What have you two done to heal the pain caused to your W? I know the two of you went to MC for awhile, but I don't remember what you two did to deal with this. Also, did you ever come clean with her the 2nd time? I remember you saying you were going to deal with some stuff before you did that, but don't remember reading that you had told her. Speaking as a BW myself now I can tell you that my radar is now always up for suspicious behavior. So, if you never did tell her...it's VERY possible she suspected. Not trying to reopen old wounds, just trying to clarify.
