How to deal with a husband that overspends money?

Me and my husband are from totally opposite “types” of families. His family had more money when he was growing up than what mine did. I’m used to the simple things and he wants everything top of the line. It drives me NUTS!!!!

He works and I am a stay at home mom (for now) while I finish school. Although he works, I don’t feel like its fair for him to just spend money left and right. We have bills (LOTS of them), a 5 year old and a baby due in 2 months. We are never able to save money because its all gone before he gets paid again. I’ve tried talking to him about it but he doesn’t listen. It’s not big things… but its unimportant things… He doesn’t go to bars and spend money or anything like that.. He just spends money everyday on lunch when he could bring lunch to work (sounds petty but 10.00 a day adds up quickly!), or he gets a 30.00 car wash when we should take that money and stock up on formula or diapers. If we go out to eat with friends, he always pays for everyone and we CAN NOT afford it by any means. I don’t get it! There are many more examples…

I probably just sound crazy but I get frustrated. I’m a long term thinker/planner and he lives in the moment. And he feels that he should be able to spend money since he works so hard for it.. which is true BUT I try to explain to him that he is not the only person that works to pay bills. As much as it sucks, thats life these days.

Is there anything I can do to fix this, or do I just need to learn to live with it? Only serious answers please. This really stresses me out daily. I hate not having money saved.
