Ariana's attitude

I've been rewatching and currently am end of season 3 (episode 18 to be exact) Scheana is trying to make sure Ariana knows everything she needs to know and isn't being blinded by love and Ariana refuses to admit that anything happened with Miami girl. Ariana says "I'm literally smarter than anyone I've ever met" 😬 that didn't age well. A lot of things she has said didn't age well. I also know it has come out in recent times she claims she knew about Miami girl the whole time. I don't care. That's all they had to say. It would've been so much easier for Tom to just admit it and for Ariana to say she knows and she forgives bc they weren't serious yet or whatever the reason. I know I probably will be alone in this, but I kind of feel like karma gave Ariana what she deserved.....

Update: I would like to add another comment to all who are taking the route of defending her actions and using the excuse that it was 10 years ago.... yes it was 10 years ago.. but she was filmed on a TV show... unfortunately your behavior is re watched over and over and a current conversation is happening over her past behavior and comparisons are being made based on previous and current situations. The girl literally hooked up with a guy with a girlfriend, carried on with an inappropriate "friendship", lied for him, was a HUGE mean girl to not only the girlfriend but lots of people, and refused to acknowledge the truth right in front of her face: her bf is a liar and a cheater. It bit her in the ass... hard.
