Me and my wife have had this deal we agreed to when first marrying. We both had good careers and good incomes when we met so we decided to split bills and home expenses, go in half on some investments and alternative retirement stuff, but then after that the rest was our own money to do with whatever we wanted. That way she had to foot the bill for her own personal stuff and I mine. Guitars, guns, and cars for me. I already had a few cars and bikes when we got married and since we've been married I have bartered, traded, modded, bought and re-sold enough cars, trucks and motorcycles over the years to get to where I am now- 2 trucks, 2 SUVs, 4 cars, 2 motorcycles. And she has a shite ton of shoes and clothes...
sounds like a great plan, my wife stays home with the kids so that doesn't work for us. It honestly is more of a time thing than it is a money thing. I tend to want to sit on my couch and do nothing instead of working on cars anymore. I have a 63 Belaire 2 door post that is sitting rotting away because I don't have the time.
