I've considered a joint account, but not sure it's a great idea for several reasons. Before she lived with me she lived with her parents, with no bills, no credit cards, and the freedom to spend everything she earnt. A joint account would financially link us and potentially lower my credit rating, which wouldn't benefit either of us. Also, our attitudes to money are very different. She sees the amount we have left over after bills as the amount we have available to spend, whereas I'm a keen saver that ferrets away every leftover penny to secure our long-term security. Given that what I bring home is roughly 20 times what she did in her last job, treating income amount as a spending target is scary concept! A weekly amount might help her budget, and know how much she has available to spend, save, plan, etc, rather than asking me if it's ok to buy something each time.
