I think in a really committed relationship there is no such thing as 'my' money or 'your' money. It is all our money, and has been since we first moved in with each other. We have a joint bank account where DH's pay goes. I also have 'my' bank account that I have had since kindy, where any pay I get goes (ie, FTB, Work), but DH has a card to this account and complete access via the internet. Mind you We also discuss any spending that takes place too, even as small as $5.
