AIBU to think it's not ok for her to tweet this about my dc?

[heynonymous]

I was reading a twitter thread and saw a reply by my ex's partner. She's mentioned one of my dc (not by name but saying he's her stepson) and used his medical history (which she's distorted to make it seem worse) to get sympathy/attention.

She hasn't been too specific, but those that know us, her or my ex will know who it's about.

I can't dm her so I tried to get Twitter to take it down, but they won't.

She's not got parental responsibility. And she's said something untrue about him. Plus I really don't think he'd want her sharing this about him to the whole world.

I'm feeling that she doesn't seem to have thought about that.

I had a quick look over her twitter feed and this looks like it's the only comment about him. But some other tweets are a bit attention seeking.

I'm not sure whether to ask her to take it down, or go grey rock?

Best policy is to ignore. Second best idea is to tell her that she is exaggerating and that his condition is this (insert truthful version) and say that people who don't understand perhaps shouldn't post incorrect nonsense (my favourite idea) I'd also ask why is posting rubbish about my ds, but I'm an arsey cow.

Do you have enough of a relationship with your ex to just tell him and ask him to have words with her about not spouting shit?

Screenshot it and ignore. If more similar follow then say something

Ok, I've screen shot it.

I've not got a good relationship with my ex due to his emotional/financial abuse. He'd probably make things worse, rather than better.

Cherry part of me would love to call her out on this but I fear the fallout.
