Always asked or told to do something different

Does anyone else have this problem? You are involved in a task and then your partner suggests doing something totally different. Or they tell you to do something they believe is important and needs to be taken care right then. Or they ask you to help them with something they can totally take care of on their own. Its like whatever you were doing doesnt matter to them and they expect you to drop everything because they think whatever they want to do or get done is more important.
