@Liskee thank you. Always good when someone agrees with you 
The Amy situation is weird. I dont like what I have seen of her. I got an odd vibe from her parents as well. In my head she has been pushed and pushed in a direction that tells you looks are everything. Family paying for cosmetic surgery, the beauty pageants. Because her parents have a very set view if what their daughter should be. Pretty, demur and, at least, semi famous. They have revealed in getting their mugs on TV on the back of her.
But I do feel for her, because Curtis had no need to do this. He went into the villa spotted the girl crying our for a good love story, never had a serious boyfriend, came across as very soft and nice. He didnt see her. He saw that they could be last years Dani and Jack. He thought he would automatically populate because he is kind of low key famous already, like Dani was.
He assumed that the public would like her and knew she would be easy to convince his feelings were genuine. Then it got away from him. She was what he thought, but came across as a bit of drama queen (they stole my thunder drama and kissing challenge drama), came across as a bit bitchy (though that could be editing) and not a lot of people liked her. She also caught far to sweep up in their love story. He tries to slow it down by asking her to be a half girlfriend. He dodnt want her getting to know anyone else, but didnt want to commit. Not committing was fair enough at that point. But he would have been better saying it was early days, let's see how it goes.
I am not an Amy fan and think she got far too carried away, ignored ther warning signs and really should take some responsibility. She cant be that unaware of her own self, to know she wasnt emotionally strong enough for this and gets overly invested. I used to be like that but I knew I was and took steps to change to protect myself. But I would feel for anyone that goes through this on national TV, whether their choice or not.
Curtis could have been a grown up and put the brakes on far earlier. He only has done so, because the only thing he wanted Amy for was to win. Now he knows that's not going to happen, he has broke it off. But, on the other hand he could have taken the cowards way out and begged her back.
I spotted ages ago he kept calling her talented. I am not saying she isnt talented or that everyone else in there is more talented than her. But what talents is he talking about? I havent seen anything that would make me label Amy as 'talented'. Is that a compliment he gives other dancers?
I found it odd at the time. I hope Amy finds someone genuine in there. But I suspect leaving maybe be better for her. I cant imagine how hard it will be for her to see him with someone else.
