<human>: Could you distill the essence of the text into 1-3 sentences?

I know this seems like a personal finance question, but the problem isn't making a budget, it's making sure both people stick to it.

I'm not gonna sugar coat it, we are both terrible with money. And we're lazy, which inevitably translates to living outside our means. The problem is that we want to deal with it in opposite ways: I try to put money aside for the things that I'd like or need and he wants to live it up as long as we've got the cash.

Our finances have been combined for years because at more than one point in our relationship, we were barely making ends meet. Now he is making significantly more money than previously, but as many months as not, we won't have enough $ in the bank to pay rent on the 1st (we have to wait for another paycheck). 

Neither one of us holds the other accountable for their spending or foolish purchases, which makes it that much easier to excuse our own. I need a solution where it doesn't feel like only one of us can live the life we want. 

Please share your stories/ideas/solutions. So many relationships crumble from money issues, but hopefully with your help we can fight through this.
<bot>: SO and I are poor, lazy spendthrifts. How can we fairly manage our budget without having to micromanage each other?
