So, what did the confrontation accomplish? You told her what you know. Do you want to know what's next? She will continue playing phone tag and twisting the truth and make you think it's all your fault.
No more talks! You need to act.
She will probably be blowing up your phone, wanting to temp check you. I suggest you don't have anymore talks tonight, phone or otherwise. She will only lie and blame, b/c she is not ready to be a faithful W.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
