Where's that money tree again?

I don't feel that we live that extravagantly. We did just move into a much larger house than we were living in (and it has cost us A LOT of money), but otherwise, nothing big and fancy going on here. I clip coupons to save money on food. We never have to fill our vehicles up with gas more than twice per month (sometimes less). I've cut eating dinner out of our current budget. I buy secondhand clothes and household items. We do have some extras (cable tv, high speed internet, netflix, cell phone data plans) but again, nothing outrageous. So why does it feel like making ends meet is as good as it's going to get? And if gas prices continue to rise, our trips to Ohio are going to be drastically reduced. I'd work if I thought that would help. Adam travels so much for work and sometimes on just a few days notice (and then he's gone for several weeks), so me working seems less likely to help, especially since a part time job wouldn't pay me enough to cover a sitter when Adam's not home.

It's just aggravating.
