A narcissist tends to view the holidays as very event-based, and the minute that the gathering or party is over, they unfortuntely go back to being miserable. They believe very strongly in always doing every holiday gathering the same way, even when it's draining and tedious for everybody (including themselves), and they are very much thrown for a loop when somebody suggests doing something differently, or, heaven forbid, a part of the family decides that they are going to do something altogether different for the holidays. The will punish you through a narcissistic fit involving tears, silence, or anger and yelling. (Remember, most narcissists resist growing or changing and don't believe that they have a need to do so, so why would they want to let anything else in their lives evolve- remember, the narcissist views you an extension of themselves, existing for their needs-not a separate person...)
HONESTLY, I hope your family understands healthy separation and the meaning of LOVE. Because it is a whole ton easier when this is not a hurdle that needs to be climbed, jumped, burned, argued over repeatedly, revisited constantly, and then, hopefully, eventually, sunk with an anchor in the farthest depths of the darkest oceans.
