I have a family member who shares a child with her ex. Said ex and my family member have been separated for a number of years and their child is now 9. Her ex has been with another lady now for about 5 years. This new partner has always seemed nice on the odd times ive met her and their child loves her ect however my family member doesn't like her although she can't articulate why and is often moaning at pretty much everything she and her ex does.
Anyway, it transpires that the exes new partner has lost a baby and she posted sharing the news on her social media, I'm not one to share private things personally but each to their own, where she explained that she'd been in and out of hospital so apologised for not responding to people and explained how terribly it had affected her mental health and so on. Until this no one was aware she was expecting.
My family member has been sent a screenshot of this by someone and has gone mad and sent messages to both her ex and the new partner saying how awful it was of them both not to tell her and lots of other things, basically made the whole thing about herself. She has sent screenshots of these on our family group chat.
Long rant short I basically told her how out of order she was, that her exes new partners pregnancy loss wasn't actually any of her business and she should apologise. We now aren't speaking. Admittedly I have suffered my own pregnancy loss and it did trigger me a bit (me and her don't always have the best of relationship anyway either).
Was I being unreasonable to call her out? My mum just wants me to apologise to stop the falling out, I don't think I need to.
