Can someone tell me this will get better; 5 year old reacting to seperation

[Louise000000]

My husband has moved out a few weeks ago and my 3 and 7 year old are handlingerie everything really well, but my 5 year old isn't. She's very angry, upset, angry at me, constant moods and huffs, angry at her siblings etc I feel awful for her. I'm hoping this is the initial adjustment and after a few months once they are in a routine, she will feel more secure.
Can anyone reassure me that this will get better. It's getting me so down.
I'm trying my best and myself and husband have agreed we will still have family meals together at weekend, they love their other home and their new room.

To be honest I think the family meals will add more confusion and likely to be more unsettling
With love and reassurance that you both still love her, and setting some constant routine things will settle down. It’s very early days for her

Me and my husband separated just over 2 years ago and both my children find it hard still but especially my DS who is the youngest age 8. He was 6 at the time and went between being very angry and aggressive which was so out of character to being upset and withdrawn.
It got easier but we have still have moments now, especially since he met another woman who he prioritises seeing over his own kids which has been another blow to them (but that's a whole different post). Just love them, be there and open to communicate. Also see if school can help mine had drawing and talking sessions at school to help with their feelings

It's so hard, feel so guilty too.
Hopefully it will settle down a bit over time
