If both my husband and I work and my husband pays the bills with both our money as he is better with financial things, should he have a right to tell me if I can and can't buy something and how much money I can spend a week on groceries?

So you're saying he takes your money, pools it with his, and pays the bills, and you have no money except what he gives to you? You have to ask him if you want to buy something that you need? Well my friend, been there done that for waaaay too many years. That's a "control" issue. That money is just as much yours as it is his. I could go on and on about this subject, frankly....no, it's not right. Grrrr.
