Read these lines from the excerpt again:
And such a luxury to him was this petting of his sorrows, that he could not bear to have any worldly cheeriness or any grating delight intrude upon it; it was too sacred for such contact; and so, presently, when his cousin Mary danced in, all alive with the joy of seeing home again after an age-long visit of one week to the country, he got up and moved in clouds and darkness out at one door as she brought song and sunshine in at the other.
These lines from the excerpt explicitly or directly state that Tom
is happy his cousin has returned
thinks his aunt likes his cousin more
feels upset that his cousin is happy
wants to continue feeling sorry for himself
