Is a wife who sleeps in another room because she is upset, knowing that her husband does not need her for that night, cursed, as mentioned in the hadith: "If a woman spends the night deserting her husband's bed, the angels curse her until she wakes up"?

If a woman spends the night forsaking her husband’s bed without a valid reason, and her husband is angry with her, the angels curse her until morning. This is conditional upon the husband being angry with her. However, if the husband initiates the estrangement or does not object to her sleeping alone, then there is no sin upon her.
