What Inference can be made?
We know its not that he is unaware of Romeo's troubles because he is clearly speaking of them. We also he is not the reason for his despair, he does not blame himself but only describes what Romeo appears to look.
Lastly, we find that he is not annoyed as the tone in his speech does not give context of this. He actually tries for a solution in lines 125 and 126.
So the answer is: He is very concerned about Romeo.
