On the boundaries aspect, I told her that her continuing to have the PA guy as a Facebook friend and continuing to text my BIL were hurting me. Per advice from the book Love Must be Tough, I told her that if she continued, then I would be forced to let my sister know what she was doing. This was my way of not involving my sister but stopping the EA.
Instead of complying, this is when my wife accused me of blackmailing her, said she would not stop, and that if I told my sister, she would divorce me instantly.
