You are understandably upset and it is showing up as anger.
You THINK she is with an OM. Would that be a deal breaker, for you?
You saw that her message said "sent from iphone". It would say the same thing if it was sent from an ipad or itouch or if she was connected to wifi and using her phone through the wifi rather than through the normal cell network.
What "answer" do you WANT from your W?
She asked to go to mediation. Last time... what...? She didn't show up? So you won't go to mediation UNLESS she shows up?
Do understand that if mediation is set up and she does not attend, that's documented and does not look good for her if it goes to court.
At the end of the day, what do you think she wants?
What do YOU want?
What more have you done to improve yourself and what more are you planning to do to become a man that only a fool would leave?
