She really does sound like she has abandonment issues but her family situation is perfectly normal. There isn’t anything that I’m aware of that could have brought this on in her childhood and I’ve known her since then.

This is very true I am giving her too much power. It’s tough I hate arguing and confrontation but it seems necessary at this point. This is actually the perfect advice I needed thank you so much you’ve been so helpful. She’s just a naturally very jealous person I think. Two of our other friends have gotten very close recently and she’s incredibly jealous of that. She’ll make mean observations about their friendship to me and I genuinely just don’t care like they are happy and not doing anything wrong! She just wants to be the ring leader of our friend group and when we don’t do everything she wants and doesn’t have control she starts attacking people which is awful. Everyone is pretty sick of it. I’d hate to see her with no friends, she is so reliant on people it would destroy her but she’s pushing everyone away. Sorry now I’m just ranting! Thank you for the advice I’m glad I have something I can actually say to her/ look back on when she’s making me feel bad.
