The psycho girlfriend (spoilers)

I know, right? Such a self-absorbed prima donna, with no compassion. The fact that her Dad was scared of her says a lot, and none of it good.

Wonder is the seed of knowledge.🐈 

I wouldn't go that far. After all, both of them agreed that they wanted the same from the beginning - temporary superficial relationship with no intentions to go any further ever. So it was Zachary who didn't play by rules. And he knew exactly what he could and should have expected from Blair. So it was correct that he wasn't too rude or blaming her too much because after all it was him to blame. Blair was true to herself, to her image and her personality, no matter if we like her or not, and it was Zach who broke his promises and betrayed both himself and Blair.

We don't have to like Blair but we must admit that she was consistent and faithful to herself, and was entitled to feel cheated. Even her arguments, no matter how they might seem illogical or ridiculous to us ("I am a model") are in fact a part of her personality that Zach accepted, even more, the fact that she was a model was one of reasons they were together.

So there is no reason to blame Blair or to be disappointed with her behaving. She kept her relation with Zach in perfect order, doing everything what she was supposed to do (having Marlee fired was just her method to preserve their relation, wouldn't every female try to get rid of another woman when feeling threatened?), but it was Zach who spoiled everything. He changed suddenly and for no reason, as sometimes males suddenly start beating their girlfriends and wives, or suddenly start to gamble, or suddenly a good peaceful young man from the neighborhood appears to be a serial killer or rapist. For a relation like the one Blair and Zachary had it would be less of a problem if he robbed a bank or two, ignored his parents funeral or revealed a next-door kid that his father's in jail (and not working in Africa as his mother told him) than letting a cat live in his appartment. It's not just that Blair didn't like cats, it's an act of emotion, something that doesn't fit in agreement that Blair and Zach, as emotionless people they were supposed to be, made.

So, no matter if we like change in Zach more than the guy who became rude and violent, it was his fault and Blair had all the right to feel angry and disappointed and unjustifiably rejected. After all, just imagine if the movie was made from her point of view, if we knew her from the beginning as the main character having a good relation that fulfilled both her and Zach's wishes, and then suddenly another woman came, jeopardized and finally ruined it...
