Jbird#2 Separated Living Together Need Advice

[Jbird]

W called at 7 am this morning and I missed her call, so I called her back around 8. She asked if I talked to D25 about the post she made, I said I don't know anymore than yesterday. She said, "okay I got to go!"

The post doesn't say who the message is to and was supposed to be only sent to a few of D25's trusted friend, but someone took a screenshot and sent it to W,

The post:

You have $(/4())? up a lot in my 25 yrs and now with my finances. Although it's not the worst thing you have done. ( then d25 rambles about not mounting debt by buying above a budget for a paragraph or so then ends with a hurtful statement)
"Exiling you from my life would be the most freeing thing I could do for myself!"

W thinks I know why D25 posted the dirty laundry, but I have said I don't know. W thinks the post is aimed at her and it most likely is. I know W is mad and hurt over this. I can't imagine my children saying that to me, I would be crushed.

Should I ask the kids to be kinder to their mother?

W will be out of town working for at least two weeks and none of kids plan on calling her or answering any of her calls.
