@Svelandria the "doesn't mind him touching her" wasn't really about her being afraid of him, but rather about personal space.
Even if there are things she wasn't taught and behaviour that she didn't learn, I'd think anyone would dislike someone just walking up to them and touching their face.
And I'd expect it to be much more uncomfortable if it's some guy she 1) just met 2) doens't like 3) saw hurting her friend.
As for the trust thing- yes, you can make deals and promises with people you dislike.
But there needs to be
some sort of trust that they keep their end of the deal.
She even felt like he was lying.
Although, in her defense, she seems to have taken the idea of "pinky promises have to be kept" too literal.
