Yep... if exposure hurts him - and he's indicated it does - then he's going to try to play you in order to keep up appearances.. even when you are alone... he somehow thinks he can fool you... and my wife DID fool me... for two months I thought it was over and she was all smiles.. i learned the hard way that ending an affair is NOT as easy as making a facebook posting.

your husband has done ZERO on HIS end to end this affair from what I have read... its all visible stuff on OW's facebook and email.. its public

What's going on in his head is going to take a LOT longer to get out of his system. The visible stuff is a START, but don't think for a second either one of them are done here... they may say they are done, at some level they may even WANT to be done.. but they have chemicals running through their systems that call teh shots right now... not their intellect... the addiction is what's playing you here.. you are trying to outsmart an addiction... and they can be very sneaky.
