It's kinda like The Zeppo where all characters showed extreme disrespect towards Xander by excluding him from that one apocalypse. He didn't hold it against them, but if it were me, I'd be really offended especially since Xander was the one who saved Buffy's life in Prophecy Girl and Willow's life in Inca the Mummy.But in stories I write where this scenario is fresh, in particular, I usually find myself writing Buffy at least somewhat alienated from the family... because I know if anyone threw me out of my house into hell's little apocalypse in the making, I would probably never talk to them again... Even when they get along, I have it change the way she relates to them. How could it not?
Nonetheless, the Zeppo wasn't as ridiculous as Empty Places - if we to headcanon Buffy's insistance not to include Xander to her experience in Helpless which happened right before The Zeppo. Empty Places simply makes me hate Buffy instead of love her because obviously the writers were trying to manipulate me into hating every single character to love Buffy and Spike, and the opposite happened to me.
