Married 15 years. Started off separate funds , but gradually all just ended up together. Been a Sahm for 8 years now. He handles all bill paying as I am not interested in doing it, but I know what the bills are . We discuss investments together .
Have credit card in my own name, and we have a joint one . I pay my credit card, because I don't want him to see what I have bought him for gifts. I don't think he has ever opened the bill and doesn't know even how to get into the account online. LOL.
It works for us, I figure If I want a 400.00 of shoes, I am going to buy them . I will check to make sure nothing big is going to hit the bank but I don't ask permission , and he usually checks with me before making a big purchase. Never know if it might have been the week I decided I wanted those shoes. ; ) Big purchase for us is over 100.00 on a "play" item.
Has worked well for us, I don't question what he buys and he learned early on, don't question me on what I spend.
The few times early on he tried to pull that card , his underwear didn't get washed for awhile ; ) lol.
