I think even if you were being nice about this, it’s clear at least that Niomi is still fully reeling from what happened. The point is if she can recognize this and slowly work on things, or if she has really convinced herself that she’s doing great and never better. Deluding herself as to how happy and great everything is, seems to be a pattern with her and has clearly not served her well in the past.
She is obviously obsessed with the idea of being single and being on ‘your own time’ and talks about it constantly. If you were really just chilling and doing your thing, you wouldn’t be writing endless captions about the single life and being radically different when you’re just a single 29 year old who has been in relationships constantly and will I’m sure be paired up within the year.
Another thing that is clear is her need to get comfort from these kind of rules and ‘facts’ about relationships and love which she uses to ‘explain‘ things that are out of her control. While yes, you could say most people experience ‘young love’ in a naive way, there are not easily sortable subsequent relationships that come in a distinct three packages. It makes Niomi feel better to say Joe was a ‘toxic’ love because she fell fast, when in reality I’m sure the situation was complex, the feelings and fallout were complex, and she would’ve confidently categorized his as ‘easy’ love a year or so ago. I’m not saying it wasn’t toxic, maybe it was, but it’s clear she rationalizes things in this way.
To me, the way she acts shows how much this incident sent her spinning, which would be understandable, but it is ‘toxic’ the way she constantly obsesses over always coming out on top and happier than anyone and better than any situation. That is what will stop her from actually healing from her breakup.
