Any SAHM's with a husband who works a lot?

I'm a SAHM and my husband is a great guy but he works a lot...I get bored and depressed at home with my two toddlers...but they are bouncing off the walls and I feel sorry for them being in the house too long, so I tend to take them out at least 5 of the 7 days a week...that gets expensive which also makes me feel bad cuz my husband works so hard. I don't go on shopping sprees,but taking the kids to bouncy places and to eat fast food really adds up...and I do not really cook! Maybe cuz I'm not good at it or cuz my life sucks all my energy out lol...how do other SAHM's with hardworking hubbies deal with this? :)
