My SD23 brought her drama to our holiday when she decided to skip her in laws Xmas Eve get together. The guy she is now living with for a year, the father of her twins goes along with her like her puppet. She said the other day to my MIL that he liked being bossed around. So SD23 shows up to my MIL' s house and despite her being a young adult with 3 kids, she wanted to talk about how it was when she was a little girl and coming to grandma's.  She got on a toy with wheels my DH and ex wife had gotten her when she was a toddler which of course my MIL brought it up.  I've heard the same stories over and over for almost 13 years.  My SIL made jokes about how dramatic she was.  But everyone seems to go along with her narcissistic behavior and feed the monster. Am I wrong for feeling this way? I am so glad I don't go that often to my MIL's house anymore because her house is too small. I love my DH but I don't want to go anymore with his family on holidays!! However, the only thing that my DH and MIL don't like about my SD23 is that she is saying that my DH is spoiling her son who is 4.  Her narcissism is showing up in how she treats them. Yet noone tells her to stop acting like a child and start acting like a grown adult who has 3 kids!!
