I lent DH the deposit for his new car. We do pool money for all the household things but keep any extra money leftover in our own accounts.
Anyway it seems he's forgotten about it. Admittedly so did I until this evening but I don't know if I should ask for it back. He's a spender, including being generous with me (although I sometimes wish he wasn't, but that's another thread!) and I'm a bit more careful with my money, but I don't know if it's overly tight to ask him for the money back.
I don't need it for anything specific, it would just go back into my rainy day fund.
