Amber's main issue was that he told Yewande his head would be turned.
That's the only time he gave Yewande is word. But what Amber and others are forgetting is that between him saying that and Arabella coming in, Yewande pied him off.
The night she was talking, loudly, round the fire pit about how she doesnt talk about her feelings and found him needy (while he was sat about 10ft away and could see and hear her), he decided to just give her space and not bother. He felt he had done enough.
24hours later she was all over him. The only thing that changed was that Arabella came in and took an interest in Danny.
Yes, I think Danny should have told Yewande he was keeping his options open. However I think amber and Anna would have reacted the same then as well.
I said it before, but imagine Yewande came over surprised him by opening up and he had said 'that's great, thanks for that. But as you made it clear you werent interested I distanced myself and now I am genuinely into Arabella. So I am keeping my options open. You good with that?'
Everyone would have been annoyed at him then.
Yewande wasnt interested. He read the signs and looked elsewhere. Then she wanted him. But he had already distanced himself. When she then back tracked and tried to reel him back in, I think he got put in a position where, it was either pick Yewande or face a lot of shit from her and the others.
If he had told Yewande at any point, he was picking Arabella, this would have happened.
Yewande clearly faked, either, the ice queen act or the affection. To stay in. But no one is questioning how trust worthy she is?
