I think if it was the other way round everyone would furious with Davide. Regardless of his lack of effort she should have had a little more respect for him and herself.
Good for Andrew for calling her out and like indiyah said, I think she's upset because she got caught. She's too much. I wouldn't be surprised if she drops jay like a sack of potatoes when new guys come in.
Makes for good telly though so it's about time some drama happened
