Final answer:
The sentence implies Ethan is willing to sacrifice his personal comfort by giving up his stove to Mattie, showing he is happy to give up comforts for her.
Step-by-step explanation:
The underlined part of the sentence "consequently the room was uninhabitable for several months of the year" implies that Ethan Frome had to sacrifice his personal space for Mattie, indicating his strong feelings for her. The act of giving up his stove, and therefore making his study uninhabitable, suggests that Ethan is happy to give up comforts for Mattie. This act of sacrifice reveals the extent of Ethan's affection and the prioritization of Mattie's comfort over his own needs, subtly indicating his emotional preference for Mattie's presence and well-being over his own solitary comfort.
