The Gf knows that I do what I like when it comes to cars... She found out the day I bought the Supra. I could have bought a holiday or used it toward putting a deposit on a house etc.
Seriously though, I don't smoke (she does), I don't do drugs and I don't drink very frequently, instead I spend MY well earned cash on my Car. She spends her well earned cash on clothes, hair ciggys etc and I dont complain so I don't expect any shit thrown my way. I take her on holiday once in a while and never neglect her and it's all fine!
Couldn't stand it if she moaned and tried telling me what to do with my money, just wouldn't take it, full stop. If your mum can't tell you what to do and what not to do then who else can?
Sound fair enough?
