I agree that you both need to sit down and talk about this, is it an easy conversation to have, NO, it is necessary. You both need to know where the other stands on financial issues and expectations. Then, you decide together what works for you. I have been married a couple of times and it did not always work for us to have a joint account. In one marriage, we had a "household" account and we each had our own accounts. We split all mutual bills 50/50 and any bills we brought in to the marriage, we each paid (I had one credit card, he had child support)
My Last marriage, I had an account and so did he, he paid all the bills, I gave him X amount out of my paycheck (an amount he came up with)
This marriage and the last one I will ever have, we have one joint checking and a savings. I pay all the bills and right now I am unemployed. He really is not involved and as long as the bills get paid and he has money to get to work and a few $ in his pocket he is ok with it. Any "extra" I make from selling eggs, chickens etc. goes to buy feed.
The key here is communication, because not talking causes hard feelings.
