Relationships and money, rant?

My s/o and I have one joint account and that is a savings for our baby. We both agreed 2 years ago when I moved in that we would keep our funds and bills separate. He pays the mortgage, his own phone, insurance, vehicle, cable/wifi, etc. I pay for our groceries, my phone, insurance, vehicle, water bill, etc. With the mortgage on his expenses, of course he pays more but he also makes like $70,000 more than I do.

So with the baby on the way... I'm kind of nervous to ask him for help when it comes to bills and necessities. Like the hospital bill, diapers, clothes, anything related to baby. We have the savings account but that will run out if I use it all towards the medical bills.

I know he will give me whatever I need without question but it's a ME thing. Like, I know it is OUR baby but I feel weird about asking for help??? Even when he offers money I am hesitant to take it. I just don't know how to get over this. I think it's my ego and it's killing me because I'm trying to shop for last minute items for baby and I feel weird about asking him to use money from our shared baby fund 😅
