I don’t get it...

So I’m due next month and my boyfriend and I had it figured out to where I’m gonna stay at home with the baby. But.... I really don’t know how it’s going to work because I’m just going off of my savings and not making any money. So all my bills I have to pay each month including food I pay for myself... I don’t know what he thinks is going to happen.. like I’m eventually going to run out of money if I’m not getting any income. It’s like he doesn’t seem to understand that. I know we have to talk more in depth about this but it seems like he never takes the time to talk about such important topics with me.. and he works a lot. I’m so stressed. How did you and your SO figure out your individual expenses while staying home? Each month I have my car loan bill, car insurance, phone bill, gas bill, credit card bill, and the electric and gas I had to put in my name so I’m paying that for our apartment as well. And I’ve been buying groceries. It’s just a lot when you have no income. :((
