You can forgive her without her asking for it, I've done that with my stbx, but it's difficult moving on until this issue is in the open. There are differences of opinion here regarding exposing the A. but I just can't understand how you can even consider reconciliation without exposing it. It was such a relief to me when I brought it up with my waw. It was like a two ton weight lifted off my shoulder. It really helped me to define the direction I ultimately decided to go in.
