Mr. Gonelong I don't like your advice so I am not going to take it
Finances are funny because they are often something that gets argued about constantly. If you find a system that works then by all means keep using it and don't stop. When my wife and I got married (actually when we bought at house) she was happy because she no longer had to pay bills. Its not that she doesn't have the money, she just is bad at keeping track of her bills. She only pays one of our bills, the cell phone, and its a crap shoot whether or not it gets paid on time.
What we did when we got married was convert everything into my checking account. My mom's name is still on the account which my wife wasn't all too keen about at the start. I have always found its a pain to get a new checking and reset all your bill pays. I do have $100 each week taken out of my checking and put into a separate accoung (great idea if you want to save money). I never had a debit card or credit card drawn off that account, I used it to pay down our mortgage, invest, and now fund our Roth's. We have a joint credit card (American Express) and each have our individual mastercard that we use when we can't use Amex and for Xmas shopping or birthday shopping. We hardly ever complain about our spending, every once in a while she will get curious as to why I control all the money, then I tell her she can pay the bills and she just laughs.
Whatever way of working your finances works don't change it. My one piece of advice is joint checking account that you pay your bills from. At the end of the day it is "our" money and it makes paying bills a heck of a lot easier.
