I guess marriage are made in heaven to complete each other

My mother in law and husband are too naive. My mother in law gave $40000 earned by my father in law, sold two land bought by my father in law in the name of business and even took
lots of money from other due to which my father in law don't even speak with her. In the other hand me, I have been working about 12 years so I know value of money and hardwork income, I will think 100 time before even spending little money. My husband needed someone who could make good financial decisions to improve their financial condition of house so I guess God made us together and even in 7 months I cleared 70% of debts created by my mother in law. Now father in law and my husband relationship have improved and I am the one to manage finances of the house. Mother in law only gets basic needs money so that she can't misuse money as she did before.
