Who is more in the wrong? DS or DD

[ML5]

DS24 & DD21 generally get on however past 4 weeks there’s been a big debate between them both to the point where DH & me had to step in. Basically each have been accusing the other of being rude & disrespectful towards each other, shouting between them both, nasty text messages & DD threatening to block DD as well on all social media. We have spoken to DD & to DD today and both have agreed to move on even though they have agreed to disagree. DH thinks DS was more in the wrong as he has been winding up DD21 and retaliating against her when she’s had enough & also said to her he don’t want to speak to her ever again but I think DD was more in the wrong as she’s been more rude & disrespectful & getting in his way more and sent DS nasty text messages saying she’s going to go No Contact with him in the future 😩😩😩
Prepared for a mix of opinions here (both pay rent before anyone asks) but was just wondering who was being more unreasonable between both of them.

the answer @ML5 it to give back some of ds' contribution so he can afford his car and be less frustrated? thought of that or how can mn help?

Need more info.

I’d be tempted to say “a plague on both their houses and stop acting like spoilt 7 year old brats”

So let them block each other and "go NC". They can have fun with that living in the same house. Why do you even need to get involved? You weren't there during the falling out so it's all he-said she-said as far as you're concerned. They're allegedly adults, let them get on with it. Either they'll get over it or they won't and someone will move out, all the better for you!

Sounds extremely childish from the pair of them. Just leave them to it.

What's the "debate"?
"I'm going to block you!" "Well fine because I'm going to go NC with YOU!" is not a debate, it's the kind of argument a couple of 5 yos get into. Did either of them say the other was not their friend and was not invited to their birthday party anymore so there?

This is also very difficult to follow as the genders aren't consistent and you keep switching between whether it's two DDs or a DD and a DS.

DS24 & DD21

Why does it matter “who is more in the wrong”? Two adults causing an atmosphere in my home would not be tolerated. They need to grow the fuck up, both of them. Or leave.

It sounds like clear communication doesn’t run in the family. Your posts are so hard to understand.

its got nothing to do with who was more or less in the wrong. It sounds like they don’t know how to deal with their own emotions.

This.

I am interested in understanding why you are now looking for someone to blame?

Sounds like both of them acted like brats and you and DH step in to calm the situation down. They’ve agreed to disagree and now you’re trying to decide who is “more in the wrong” 🤷🏻‍♀️ I don’t get why that matters now???

I can’t tell, they are both behaving badly. They really need to fly the next and grow up, but especially the 24 year old.

They need space from each other.
