Thank you!

so it’s getting down to the wire and I wanted to just ask for some advice re logistics.
As you know, I’ve been keeping things neutral around the house for the sake of my two daughters, ages 12 (just turned 12!) and 13. IRS Christmas as you know and my plan has been to wait until right after Christmas to tell them anc to start moving out.
they’re leaving for their grandparents house late Christmas morning after we spend Christmas t morning together. I sat down with my husband Friday night to make it clear that I was going ti start moving my things out Christmas afternoon and spend the week in between moving things. And that the big movers were coming Jan 3rd.
he did not handle this news well even though I’ve been telling him for over a month what my plans were. He then started trying to sell me on he would help me move my things , that we should do it “together” and that he was under the impression we would share a mover for the big things.
thus is Not at all what I’m planning as I plan to do this separate from him. I want ti make this clear to him but at the same time it risks him turning very nasty right around Christmas.
I was planning on just telling him on the day of that I’m doing this separately

I’ve been reading on narcissists and it says that there’s no good way to give them news they don’t want to hear

I’ve been clear with him for over a month now and even tried to bring up logistics of the move and he’s only buried his head in sand trying ti love bomb me. So I don’t feel I need to babysit this at this point plus I’ve come this far keeping the peace for the holidays w the kids.
Wheb he suggested he help me move I did not agree but I didn’t fight it either. He was starting to get hostile so I just backed away.
Bottim line is I’m not sure if I need to bring this detail up again with him before the actual day or leave it be. Thank you !
