Reply #598: That does presume that he and his wife were still having sex.

Which would explain his behavior, if not exactly excuse it. It would also explain why Elizabeth is so forgiving; if cancer and chemo killed off her sex drive, she might have even given him tacit permission to have affairs, as long as they weren't serious.

Now all of that is just conjecture on my part, but it does go to show that you shouldn't make angry assumptions that make him far guiltier than he really is.
