Is the husband obligated to continue providing the basic necessities for the home and accumulating what remains, or to fulfill the desires of his wife and daughter for luxuries that require incurring debt, knowing the limited salary and the existence of other debts and obligations?

If you have provided your wife and daughter with their necessities of food, clothing, and shelter, then you have fulfilled your duty, and your wife should not accuse you of negligence. You should be patient with her and advise her. If you can provide more for them without extravagance, wastefulness, or undue burden, then do so; this will improve your relationship, bearing in mind that settling an immediate debt takes precedence over spending for the purpose of expansion.
