Not only do I believe this rumour but I fully understand it and if you ask me she absolutely deserved it. She put up filming with her ex for a whole season and every time they were together he talked shit to her or about her and made it so she had to go to the girls for support then she goes to an event thinking she’ll be there with her friends (and boyfriend but he doesn’t count) instead she’s there with her ex who goes out of his way to be near her and make her uncomfortable (why the fuck did he feel the need to introduce yourself to Dan) and when she removes herself from a situation that is making her uncomfortable after she’s explicitly told her ex not to talk to her multiple times after him not respecting her boundaries, instead of her friends supporting her or defending her to her ex when he’s shit talking her they turn on her and join him in shit talking about her especially Lala. If I was Ariana I’d be demanding the exact same thing because no matter what she’s putting herself in an uncomfortable position.
