Starsky, Thanks for the reply and thank you for the advice. I certainly see what you mean.
She is not aware that I know yet. I am not sure when I will confront her. I don't think this will be a wake up call for her at all. My issue is that she is still living in the house and I am not sure that is healthy after confronting her with it. We have young teens at home and I am concerned about them more than anything else.
Sorry to hear about your W's encounter. Did the marriage recover?
