I'm thinking of purchasing a new pair of heels for work from our joint bank account
Is there something that you need?
I need a new pair of heels because I'm planning to attend a special night event but I don't want him to know.
It is okay to buy things from a joint account as long as you tell your partner. It is important to share information when both people are using the account so that it won't be over drafted.
I can't. I'll wait till he's not looking.
He's going to find out eventually, so why not tell him now? It's a joint account meaning it's both of your money, I'm sure you can work this out by talking to him.
