A wife has enough money. She spent a lot in sadaqa. Help people. Her husband is in dept for spending the daily expenditure. Has she responsibility to help her husband. Can she spend all her without caring for her husband?

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
Indeed giving sadaqah (charity) is a virtuous act. Whilst it is not an obligation upon the wife to help her husband, morally and ethically it would be highly imperative to assist him in his financial woes. In fact spending on her husband and family will earn her double the reward she is getting.
Consider the following Ahadith:
Abu Sa’id RA narrated that ‘Zainab the wife of Ibn Mas’ud came along and said to the Prophet “O Messenger of Allah ﷺ!You have commanded us today to give Sadaqah (charity). I have some jewellery of mine and I wanted to give it as Sadaqah, but Ibn Mas’ud claims that he and his children are the most entitled to my Sadaqah. (Deserve it more than anyone else.)’ The Messenger of Allah ﷺ said:
“Ibn Mas’ud is right. Your husband and your children are more deserving.’’
Nabi ﷺ mentioned:
“Charity to a needy person is a charity. But charity to a relative entails a double reward: The reward of charity and the reward of maintaining ties of kinship.”
In another narration:
Umme Salamah RA narrates: “I asked: ‘O Messenger of Allah! Will I be rewarded if I spend on the children of Abu Salamah? I cannot see myself leaving them like this [going around and begging from people]. They are my children.’ He replied: ‘Yes. You will be rewarded for whatever you spend on them.’ ”
Nabi ﷺ has also mentioned:
“The upper hand is better than the lower hand [i.e. the spending hand is better than the receiving hand]. Commence by spending on your family first. …
