Folks missing the point of the story I see.

The thing is both of them have right and wrong in their motivations, it’s not a black and white binary here. Rick went from encouraging healthy relaxation (which is basically the extent of Rick’s “being right” in this scenario) to unhealthy indulgence, you see this shift when he stops caring about Summer and Morty and tries to send them home so they’re “out of the way.” Unity recognizes this eventually, which is why she leaves, she realizes that Rick’s still volatile and dangerous for both of them. She handled it in a poor way that did a lot of damage, but the end result was for their mutual benefit.

It was Rick’s continued self destructive tendencies soloing in on Rick Prime that not only got Unity’s attention, but caused him to ignore her messages. She did the right thing by reaching out an olive branch. Maybe she was a bit out of line assimilating Virginia, but that was basically her way of showing up at Rick’s door to do a wellness check. You even see it on Rick’s face at the end when she says she’s “stopping by Virginia,” because yeah, all he had to do was check his messages, and all of that trouble with Curtis and the pain he caused Unity by making her release hundreds of millions (something he clearly seems to lament when trying to help her up) could have been avoided. You see that realization and regret in an instant, and it’s been very clear that Rick has been VERY bad with relationships of any kind through all 7 seasons, but he is getting better and able to realize his mistakes a lot easier than before.
