Dude, not all of us are so cool in the presence of exes. Most prefer to burn bridges, and the girl still living at her ex-boyfriends mom's house should have moved on with her life long ago.

That would be really uncomfortable for anyone trying to win the approval of a possible future in-law. A compassionate mom would hang out with ex-girlfriend on her own time, not parade her around on Christmas Day as if to say "Thanks for bringing this angel into my life son, she's just like a daughter to me!"

Being a monogamous straight girl prone to jealousy I found Dan's response unnecessarily mean. I would have said DTMFA: if he's unwilling to see how much this behavior bothers HMMN and have a talk with his mother, They're not right for each other.

Likewise, if my dad was goofin' around with one of my ex-boyrfriends, I wouldn't want to come home for Christmas, let alone bring a new flame along. Yuck!

@1. It's one thing for the BF to be opposed to seeing his ex-GF, & another for the new girl to think she has the right to dictate family life to her boyfriend's family. Nothing in the letter indicates that the BF was particularly traumatized by the incident.

I have an ex whose ex hung out with his family. He hated it, so I was sympathetic to him. If he had been OK with it, it'd have been my responsibility to either get over it or bow out gracefully. Either way, pouting over the holidays would have been childish.
