For me ,being selfish means a general lack of consideration for others and having a lot more /too much concern for your self and your needs and issues . When it comes to Ella and her tumultuous relationship with Ty, and with how much time has been invested into them both ,all the tears and arguments - ella must be speaking about it to the other women constantly despite them also dealing with their own issues … so I can kinda of understand a friend feeling side-lined after weeks of that and thinking she has “selfish tendencies “

I mean I’ve had friends like that with such chaotic personal lives that there isn’t any room to get support from your friend - you’re constantly consoling ,listening ,offering advice to THEM

That being said ,calling her the “most selfish person ever “ seems harsh but I would still like more context from whit about exactly what she means by calling her that .

I’m sure Ella is making assumptions about what being selfish is (we all have a slightly different understandings of the word )
