Is the wife cursed or sinful if her husband becomes angry due to a misunderstanding on her part, and he refuses to return home despite her attempts to apologize and clarify the situation?

What the husband is doing contradicts Allah Almighty's saying: (And live with them in kindness) and the Prophet's saying, peace and blessings be upon him: "It is not lawful for a Muslim to forsake his brother for more than three [days]," and the wife has a greater right to that. The husband should accept his wife's apology; because of the Prophet's saying, peace and blessings be upon him: "Whoever's brother apologizes to him with an excuse and he does not accept it, will bear a sin like that of a customs collector." If the wife is sincere in her repentance and strives hard, and her husband does not forgive her, then there is no sin upon her.
