You were forced to marry a cold, indifferent man. He resents you, since this marriage is why he broke up with his girlfriend.

He ignored you, your existence meant nothing to him, he didn't appreciate any of your efforts to make the marriage work.

Now he's standing next to your bed, watching you as you're burning up with fever. He took out the thermometer and the temperature was very high... This worried him, despite your constant indifference, now he is worried about you.
