My DH and I have no "pocket money" we simply just use the credit cards and pay it when it's due. Both our incomes go into a joint account and it's split into different pots/payments each month. We don't have separate pots for a couple of reasons, but mainly because I personally don't need it, and he abused our joint finances for a few years, and that was the only way to prevent it from happening again.
Normally there's no real issue, until there's a birthday present to buy as he feels he's spending "my money" I make almost 3x his salary.
He feels bad because he doesn't feel like he's buying a present with HIS money. I try to reassure him it doesn't really matter, but he seems a bit heart broken about it.
