He must have disliked her. If they hadn't rented the house together, they wouldn't have interacted at all. If a male classmate wanted to share the house with him at that time, I believe he wouldn't have refused.
He is very sensible, very pragmatic, has a high degree of education, a good job, a good income, a good future, and may be a bit utilitarian. He has lived with her for two years and has never exceeded her. He will not interfere with her privacy, just as she will not pay attention to his habits.

Is it because he is a decent person? Or is it because she has no feminine charm and cannot excite any man? ? ? (She thought desperately: maybe the latter component is the majority)
Or maybe he simply hates her?
