Yes, unfortunately, they can absolutely have an affair and act normal the next minute with you. My H was having an affair for 6 months and was actually telling me that the M was in trouble because of everything I was doing. Not saying I was perfect, but I certainly didn't add to our problems by cheating and lying about it.

The real question is, though, would it make a difference if there was an OM? Would you still want to reconcile and try to fix your marriage? If so, there's probably no reason to go snooping and find out. Just keep DB'ing by detaching, GAL'ing and meeting your 180 goals.
