Budget Woes

Writing a budget is not my favorite thing to do. Unlike some people, it is not sticking to the budget that is a problem (though the amount of money allotted to me in the budget may rub me the wrong way, I'm still fairly able to stick to it), no, it is rather the ACT of writing a budget that really irks me. I don't much understand it, really. Aside from saving every single receipt I get, and spending hours in front of a spreadsheet, there is really no good way to go about it. Everything else is just guessing.
Plus, who honestly spends the same amount month-to-month? I know it is supposed to all "even out in the wash" over time, but the stress of watching myself go drastically over one month, and then steadily slightly under the next five- in my effort to make up for that one month- is just too much for me.
Perhaps it is the entire story that really gets me. I could tell you roughly how much I spend a week on groceries, gas, and what my rent costs, but can I get close enough to stake my entire budget on it? I don't know...what if this week I needed lots of condiments? (things you only buy a few times a year) but last week I only really needed milk? Do I find a happy medium? You can sense my dilema here.
So here is my preference. I want hubby to watch our finances and come up with a schedule of what we typically spend, he likes that stuff anyways. Then I want him to lay it all out nice and easy for me so that I can look it over, pretend I totally understand, nod my head and go on my merry way with what I would affectionately term an "allowance" for what I can spend on groceries, myself, and him (as I inevitably buy his clothes as well as my own) each month.
Is this wrong? I have no ambitions of being a 1950's wifey with no clue as to what is going on, I'd like to be kept aprised of the situation...however how much I am actually involved is not really of any concern to me. I'd just be happy to spend the money...
