My take on the Tash and Andrew situation is if they could step back, they're both saying the same thing -
He said she was being fake with him.
She said she wasn't being herself with him.
So he's right - and from his angle, she was telling him she was falling in love, tunnel vision etc, while trying out Jay and Charlie but getting outraged when the guys shook their heads. She's been all over the place, mainly because they were voted as an unpopular couple and from that moment on, she was casting around and desperate to show this other 'sassy' side that she's convinced she has. But before CA, she was being unequivocal with Andrew about being into him, so that's how he went into the situation, only to hear from the new girls that she was taking him for a mug.
His Coco fling was classic rebound and he clearly still is into Tasha - which is a VERY different scenario to her situation with Billy. Which is that she went into CA claiming she was falling for Andrew, but met Billy, decided she was more herself with him so copped off with him. There was no trigger like Andrew had - she just decided she preferred Billy and that she hadn't really been herself with Andrew. Which is totally her prerogative. BUT it backs up everything Andrew was feeling - that she wasn't being real with him and really wanted someone else all along.
I think after that last chat he came out of it well, showing his feelings for her were genuine, he was hurt and upset but understanding and wished her the best. He's big enough to not be entirely wrapped up in himself, whereas I think she's still ever-alert about how she's being thought of and all that matters is that she's all right, Andrew's feelings don't really matter. And I don't think she's really into Billy that much either. He's a grinning berk who was handily there to ego boost.
Bottom line though, she was being fake/not being herself and they're better off apart. It's a shame that Andrew's stuck with Coco because ideally I'd like to see if him with a more compatible girl would be more popular than Tash and Billy.
On the other matters - I can't wait till news gets to Davide in some form about E-S's wandering hands with George. Not cos he'll genuinely care that much, but they'll both play it out as a good drama.
Whereas Jacques is being horribly toxic pushing the blame back on Paige and I can't wait for her to escape his clutches - into Jay's arms perhaps. We'll see...
