Late to the Vanderpump game, but Ariana Season 4. Wtf?

So I just started Vanderpump and I’m on season 4. Just finished up episode 18. Ariana is absolutely unbearable. I never liked her, from the beginning and she’s just making it so hard to watch. I read threads from 8 years ago and it seems like everyone is always on her side. But I don’t get how?! She’s selfish, self absorbed, obsessed with Kristen even though she’s moved on. How did people like her 8 years ago?? And please tell me she’s matured over the seasons because I need that hope to keep watching lol.
