My fiancé (not married) and I live together and have separate bank accounts.  He is currently deployed overseas with the Army.  He transfers a scheduled amount of money each month to me through Zelle to pay for his bills here at home, help out with car/home repairs, pay for his kids extracurriculars, etc.  I keep a separate check register just for this money.  How can I show this is not income for me?  I am paying expenses he would have paid if he were not deployed.
