i am no expert here by no means, but is sounds like everyone knows she is having an affair with this guy so exposing her really will have no affect IMO. he is obviously not married so again nothing exposure is going to do...but exposing your W texts to him might help deteriorate his illusion of the R he thinks he has with your W.
Not sure how this guy thinks having boundries in his R with your W is going to work when in fact she is still married to you.
my thoughts are GAL - she is bouncing between the fog of having an affair and having a family....she is going to have to choose. take time to work on you, because no matter what happens you will still be there in the end.
again i am not the best person to ask knowing my story - good luck
