My mom's mother she helped my father by giving him debt also my mother gave her own money to help him. Once my father was in prison he had 90000 dirhams in his savings then my fathers friend betrayed my mom by saying that he would take him out of the prison with those money. Now whenever my mom discuss about the money she and her mother gave to help my father but father refuses and says to my mother that you also wasted my money. Is my father's argument right?
