Narcissists only do what they want to do. Because they have
low empathy, they simply cannot consider other people’s feelings, and so if they want to do something/go somewhere/have something they will insist that others comply with their wishes, trampling all over their boundaries and needs.
You may give up trying to object, and may develop ‘co-dependency issues’ where your own needs are so infrequently heard and met that you stop having them altogether - instead focusing on meeting the many needs of the narcissist.
