If you go all the way through all the LBS threads, there are a list of rules. Here: http://www.divorcebusting.com/forums/ubbthreads.php?ubb=showflat&Number=2551824#Post2551824 Check out #10. Its done now, but in the past you should have insisted on transparency and then you would know whether she is in an A or not. If she brings up the R conversation again (only if SHE does), then I'd casually mention how this seems eerily similar to when she had an A and ask if she is having one.
Prior to reading threads about Affairs, I was inclined to think the same thing as you. I'm not so sure now. Obviously you call though. Anyway, the rules arer a little different with an A, so I'd keep trying to see if she is in one. My sitch is very complicated, but if she is only a WAW its harder to figure out how to act IMO.
