I bad at this too. But for me, she was being very antagonistic “i dont want to talk to you” yet was shouting abuse and giving him the finger for a reaction and then shutting him down when he tried to calmly speak. She was trying to get him to lose his temper, he bit a couple of times by calling her an idiot and a twit by kept walking away. This is to make him seem as bad as her, deflecting. She was parading around the villa shouting at everyone, she was given plenty of opportunities to talk rationally but she carried on.
Then later when she gave him the opportunity to chat, she was responding rudely. I don't know how he tolerated it for as long as he did.
She had better apologise to every single person in that villa and be genuinely sorry for how she made everyone feel.
