How about putting that money into the bond instead and leaving the g/f to fend for herself? Duuuuuudes
Seriously
Either marry them or prepare to have your nutsack handed to you
LOL, I earn more and have a better credit-rating than she does, and my car's paid for so it made sense for me to buy her car. We live jointly from our incomes: she pays for cleaning lady, ADSL, food, rates, electricity and levy. I pay for the car, bond and insurance. We are married to all intents and purposes.
Nutsack? Don't you hand that in at the door when you move in together???
