I agree and on top of that, Hollyhock had also her own issues to take care of.
Body Image for example, she was uncomfortable with her weight and Beatrice drugged her to make her lose weight.
Trust issues (after Bojack deliberately tried to buy drugs while she was around, even knowing that he needs it for his pain, the methods he used were all illegal to say the least. And the way Bojack had Hollyhock to sneak into Gina’s house.)
Hollyhock was bound to distance herself from Bojack, it was good for her that she did!
She had to;
(that she ditched, but his methods were shady to say the least)
Rude or not, these are more than reason enough. If you had a history similar to this with your ex, would you break contact?
