I think a lot of families don't budget very well and end up over spending. We have a nice budget, it is very hard to get used to at first. But completely worth it. We have money set aside for eating out and for groceries.
When we first got married, we didn't budget we just spent on what looked good and what we wanted. As time has passed we have learned that it is worth suffering a little today and not eating out or not buying that pair of shoes so that in a month or two we can buy that nice couch or tv. I coupon and stockpile to help us save a LOT of money and make the money we do make go SO much farther.
I think you have to learn to be responsible and not use credit cards, live on what you make and life is so much better. A lot of families fight over money issues. It is stressful to not be able to pay all the bills or buy whatever item you want today. But once everyone is on the same page about where money is to be spent, relationships will improve.
