Is there an expression or idiom describing a situation, where one person does some (perhaps irreversible) action or makes an important decision, without consulting another person. Thus, putting the other person in front of a fact? It exists in my language and I wonder if there's an English equivalent.
This is similar to "fait accompli", but the emphasis is on the inconsiderate behavior, rather than the potential irreversibility of the action. However, this isn't the same as acting behind someone's back, because it has no sense of acting secretly or sneakingly. E.g. a husband says to his wife: "My boss asked me if I can stay extra hours today and I agreed", and she protests: "You should have asked me first! I wanted us to go to the Jonsons for dinner".
