My wife likes taking care of me, and I'm tired of her taking care of me. Last night, I went out and had a quarrel. Why did she care about me when I came back to sleep?
This may be because you still have some feelings and love for each other. Although there are some frictions and contradictions between you, you are still very concerned about each other's life and needs. In addition, what you need when sleeping is a sense of security and comfort, and your wife may take care of you because she cares about your sleep quality.
