I believe this line clearly shows that she has been trying to nod at him positively and that she's got tired of/from doing so unfortunately.

And here's second question.
In that case, how can she nod at him positively while she doesn't look straight at him?

Question 1
This line shows that she has been trying to nod at him, as you say. But she might not do so POSITIVELY. She might do so unwillingly.

Question 2
I think it's possible enough.
