money honey ...

my boyfriend (16) is working a minimum wage job (7.25 KS) and I'm 17 and going off to college in a year and my mom is contantly on my ass for saving money and I'm doing my best. I'm working an 8.00/hr job and I'm saving $100 a paycheck (every two weeks) out of a paycheck that is usually about $115-125. my boyfriend wants to start working extra hours to help give me some extra money and wants me to put the money in my bank account without telling my parents where it is coming from... he said "it's not my money, it's ours"
