Is the retirement money that I took and spent on my niece, along with household expenses, considered a debt upon me?

The salary of the two daughters must be spent on their basic needs and educational expenses. The poor guardian overseeing them may partake of it in a reasonable manner. If the guardian spends the salary on the two daughters, there is no fault on him, and he is not required to repay anything. However, if he takes from their money without necessity, he must repent and return what he took unjustly. If he is unable to ascertain the exact amount, he should pay what he believes will most likely clear his liability.
