Completely agree.
As unfair as it is, they can't avoid eachother forever, as much as they may want to. It's easier to deal with now than when forced to deal with it through difficult circumstances.
Whatever your views on Nadia and Julia as people, I think most would agree that this isn't a healthy way of dealing with trauma. Nadia and Julia just need to realise that it doesn't matter who did what and how they got to where they are now. Of course, both need to realise that and be willing to have that happen.
Their feud is also, in my view, quite selfish. It impacts the entire family and puts everyone in an awkward position.
It would clearly benefit the whole family if it could get to the point where they are comfortable being in a room together making polite small talk. They may never even be friends, but it shouldn't be unachievable to just have polite conversation. The entire family would breathe a sigh of relief.
It's gone on and for so long, and it sounds like their family have been enabling it by trying to keep the peace in keeping them separate. They have to do two of everything - two mothers days most recently. Can you imagine living that way? Very sad for all involved. A therapist or counsellor would do them wonders.
Both Nadia AND Julia need to stop fanning the flames on social media. As much as I do love Julia and loved seeing Nadia being called out, Julia's post was never going to go down well. Not that that excuses Nadia's fans/families response.
Both of them need to let it go, meet in real life, and talk about something as inoffensive as the weather. Your parents, children and other siblings would appreciate it.
