In regards to the apology...how sorry are you really? Do you think exposing to her mother helped put a stopper on the EA continuing? Would you do it again if you could go back in time?
I understand why you told her mother and I did the same thing. I was desperate and thought friends and family could talk some sense into her. It may be that was some of the reason why my W asked for another chance. She may have wanted to try and "save face" with those that knew.
Have you been in touch with Goldeylox in the last couple days? I will try to call her tonight and see how she is doing.
