I am European and I would be really angry if that happened to me.... please dont think its an Asian thing.

In English we say 'what is good for the goose is good for the gander'...as Non Merci said.... if your husband thinks his behaviour is ok....then why don't you go out with a guy 10years younger????? See if he thinks it is ok. Give him a taste of his own medicine and then he can see how sweet his ego trip is.
