I wish I had not contacted him. It just got to me what my friend informed me of... I wasn't sleeping and I should have absolutely taken the route... when in doubt do nothing.
Hi KitCat, sorry you had a rough morning. This exchange didn't change that he was already in a PA and announcing it to his friends. Now that it's in the open, this seems like a powerful opportunity to take action such as moving his things to the guest bedroom, directing all future divorce conversation to your attorney, and starting to move on. These actions preserve your integrity--you are not the kind of woman who settles for a lying cheater. This may also introduce doubts his Plan B is leaving and divorce won't be all rosey.
