I do think Amy intended to stay the night of the dumping.
I also dont think it showed that Maura isnt interested in Curtis that much. She chose to save her closest friend over some guy she was getting to know. It would have looked like she was putting a man in front of her friend AND that she was condemning Amy to watching Curtis crack on with someone else.
I imagine she left by mutual agreement. She didnt want to meet someone else at this point. But having her there was preventing Curtis doing anything either.
The producers managed to sort it out, so the 2 people in the villa that had no interest in actually meeting anyone else (Amy and Lucie) went home.
Part of the reason, ita getting quite boring is because theres quite a few in there that dont want to meet anyone. Amy, Lucie and (it seems) Amber are too wrapped up in one person so they arent open to meeting anyone else.
Amber will be the next to go, unless Michael recoupled with her or she gets over it.
Curtis doesnt really want to meet someone, I think he will go as well, if he doesnt change now Amy has gone.
The producers are thinking (in my opinion) that Amy didnt want to meet anyone, but let's see if Curtis cracks on with her out. Amy wouldnt have cracked on if Curtis left
But Curtis might.
I think both Curtis and Amber will be manoeuvred out if they both just arent interested in meeting anyone new.
