May or may not help with friends talking to her. If I remember the book right MWD said it could potentially help but backfire just as well.
Our best couple friends are just like yours that you mentioned. We did everything together. The woman actually tried giving my W the benefit of the doubt but still condemned the A but wife just ran even further. My W is now just worried about her image so she constantly asked me who I told. I may have told 4 trusted people just trying to keep judgement down. So I guess what I'm trying to say is if the pepole won't agree with your W, she will prob run further. Not to say she won't realize the loss further down the road. Totally understand your predicament.
