While I do think that even when you are the one to end a relationship, you canstill mourn it in some way, I also believe she was dumped.

She did say she didn't see the changes coming, and she truly is too self-centered to read other people (see hamptons vlog where the Ross are obviously hostile/unimpressed and she just flits about being a brat).

She had kids and refused to be a mother. So she turned into a resentful brat towards Don and though she was the victim of his dreams/desires and punished him, but though he'd just stick around to take it. Instead, he dumped her.

Then, she aknowledged the divorce, but though her life would otherwise stay the same as far as the in laws were concerned, without villanized Don around, so good ridance.

Then, Utah trip happened, and she couldn't read the situation right (Ross' feelings towards her, etc.) and, as someone else put it, overplayed her hand being again an entitled brat. Then, she was freezed out for good.

As someone else said, I predict a last shock as pandemic ends and she remains isolated because without the Ross', there isn't much social life, and her "ride or die" besties, her "tribe", clearly aren't there for the long haul - they were there for the crisis, maybe genuinely so, maybe for the subscribers, maybe for the tea - but again, I think she either misread the room or overplayed her hand with the relationship she has with the planner ladies (especially the Erin Condren representative, which probably dropped her after the disaster of the review videos (rose gold,iiiick) and the "Do better" story). And both "ride or die" proclamation and the entourage apperance at Donnies Party last year were, at best,teenaged moves, of someone who doesn't understand how to behave in adult situations, IMO.
