The mechanics of how the two of you will handle your finances really isn't the issue. Many couples in successful marriages have separate checking accounts and many couples in successful marriages have one account.
The issue is whether or not the two of you can calmly and practically talk about money.
If how your money is spent, or saved, or not spent is an issue before you get married, it will be an even bigger issue after your wedding.
If your future spouse doesn't want to talk about money, or doesn't think talking about money is important, postpone your wedding until this issue is solved.
