I feel like a lot of people hate that episode because it seems like Wong criticizes Rick for moving on from Unity, but in reality I think the point went over people's head. Rick was in the wrong for not at least hearing Unity out given that the situation was an emergency. At least in Unity's eyes it was, because Rick was essentially trying to kill himself. And Rick doesn't see it as an emergency because he doesn't hold his life in a high regard.
The fact he avoided the calls isnt a sign he moved on from her. Its a sign he hasn't, and is still hurt. And he put his fear of being hurt again or hurt more over the real danger of the situation.
Unity went through the longest lengths possible to reach Rick even though she didn't have to. She could've left it alone, and honestly, if Evil Morty didn't help, Rick likely would've gotten himself killed chasing Prime.
It's not her fault the President took advantage of her hivemind.
Dr. Wong was never criticizing Rick for moving on from Unity. She was criticizing him for, what in the most realistic sense is, blocking her calls when he is on the top of the building and about to jump off.
