Like JRuss, I don't know whether or not confronting your wife is the right thing to do. I also agree with JRuss that deferring to a vet is probably a good idea. However, I did want to mention, that it seems like many spouses that are having an EA are in complete denial that it's an affair because there is no sex involved. Because of that, in some ways an EA is more difficult to deal with than a PA. If there's a PA, then it's harder to deny that there's an affair. The common excuse that is used in an EA is "just friends." Just be aware that EAs are just as destructive as PAs.
