For me, I think she has gone from being relatable to not being relatable. She is acting so casual about this whole thing. She got a whole cohort of followers going through similar & I think if she just mentioned how it has worked out for her she wouldn't get any backlash but she seems to be implying this is how it should be for everyone - she did have a history with this fella so obviously they breezed through a lot of the early relationship stuff that can take time for others & if she was vulnerable she obvs trusted him, which you may not be so with a brand new partner.
I am glad she is happy and she genuinely does seem to have moved on, but I think she needs to remember a lot of her followers could be alienated as they aren't getting the perfect insta happily ever after. I know she isn't obligated to share everything but she did share a lot of the break up and that did elevate her popularity as people wanted to support her.
