What’s your money arrangement — what’s mine is mine or what’s mine is ours?

As I am not working, his money is my money. My pocket money is my money. Some big items in the household I need to get permission from him first before buying, including children's enrichment classes. I am kinda missing those days where I have my own income and spend on the things I like. I guess this is the trade-off of becoming a full time mother. But I never regret of taking care of my kids full time at home.
