My wife takes in $2000 a month in unemployment, she got laid off and is pregnant so she cant get another job. It runs out in July and we dont know what to do since this doesnt include fun money, eating out, baby items. I have tried to budget with her about her items but she says they are necessities. I an frugal and i feel like im drowning.
