🌊🌊 Venus 🌊🌊
We own a home and two cars. Our bills and mortgage are very low we are able to save money easily neither of us spend much money but we don't budget either we just try to save as much as we can when we spend. I go to school full time and work part time his new salary covers what he and I both made together and then some. We have one child and one on the way. Should I take on his offer? What amount of money would your significant other have to earn in order for you to be a stay at home mom?
