[It would be a lie to say he wasn't feeling any frustration at all with this situation. But he's trying to be as patient as possible. He's made himself perfectly clear and the only one who is showing signs of hesitation is her. He's trying to reassess his 'game plan' and determine if he needs to do something else to get her more comfortable.
And so he just turns away from her and starts walking without looking back.
She obviously needs to work a little for things. So it's not just him doing all the legwork. She needs to be making the choices directly.
But he leaves one of his hands free as he walks. Just in case she feels like grasping it. But she needs to be the one to follow.]
