I still think, after reading all the other responses, that this behaviour is unusual, but not unusual in high functioning Aspergers. Now I’m not a doctor, but I do know a fair bit about Aspergers, and this lack of seeing a need to tell his closest relative, his wife, what he was going to be doing, sounds very, very much like the behaviour of a high functioning Aspergers. The facts are, he didn’t see a need to consider his wife’s feelings, or what she might be doing during the time he usually spends with her. He didn’t see a need! She also says he’s quiet, and gets on with his own activities during the week. Come on ladies, if he doesn’t see a need to inform her until it’s already arranged, and has shown nil interest in what she might be doing whilst he’s away, that it not usual.
