I know this isn't easy, and I fought the concept when someone first said it to me, but try to wrap your head around "it's just sex." For some reason, for us guys, that's much harder to do, but for WOMEN, I'm tellin' ya, it's the EMOTIONAL attachment that means more to them.
Now, it could very well be that she has BOTH an EA and a PA going on here, but even if that's the case, what I'm saying is that there's really nothing new about getting this recent revelation. Your plan should still be the same.
At first, it was the sex that bothered me the most when I learned of my wife's affair. In time, it was the DECEIT that hurt me the most, and in time, it was the DISRESPECT of it all.
