Stay at home mom.

So I plan on being a stay at home mom. I am due at the end of June. I stay at home now. But we are overseas. I plan on getting a job once we move back to the states which is next year. But right now I just feel horrible because if I want to buy something (I always find sales and what not if I do buy somthing and I always ask first) I feel horrible even if he says yes he doesn't care. I mean he works he earned that money. I just feel bad for spending the money. (I don't spend stuff on myself all the time just here and there) I know it's "our money" since we are married but I still feel bad. :( sorry I'm 33 wks Prego and emotional
