I find her so grotesque. She did the worst possible thing a female could do to their friend, and has shown zero remorse throughout. Instead, she's played the victim and tried to deflect onto Inga and make her look like the bad party. I think Yaz loves the excitement of chasing after toxic men, hence Miles and Sam. It clearly comes from a place of massive insecurity and hinging one's worth on the validation they get from male attention. She's ruthlessly pursued that fixation at the cost of her friendship with Inga.

You can tell he's regretting his decision big time. There's no chemistry whatsoever or interest from his side in pretty much all the Australia pics, including the damning ones on the DM website. He obvs bored by her now he's won her over and has nothing left to chase. Including Inga, now she's cut him off dead.
