Ok I think it was a fantasy, I can see nothing that points to a PA. Since she told me we've grow apart we are getting along better than ever. She is just really confused right now and we talk casually all the time she initiates. Its been 8 days since we have had physical contact but I sense she wants to.
Do not read into what she is saying to you. My XW had (at least) an EA towards the end of our marriage and we still had intimacy almost all the way till the end... She also seemed confused, which I assume is natural if they are weighing their options. So just be careful and as Cadet mentioned, get the DR book asap.
