32 weeks and martial problems

I am really scared and concerned as I get closer to having this baby...

Me and my husband have 1 boy each from a previous relationship and our daughter together and now our son coming soon...

Well we have split a few times and decided a few months back to try again and work on our marriage.

He wanted me to be a stay at home mom and promised he would take care of everything..

So I quit my part time job, well I ended up getting some money and ever since he found out I get a little money now monthly he hasn’t even offered to help pay for my bills and I’ve been shelling out 500$ every couple of weeks for groceries.

At first I didn’t mind, but now it’s like I have to take care of all my bills and groceries and the stuff for the baby and kids

I have no access to any money other than what I get myself....

It’s caused some issues when I brought up my concerns he just gets mad and says why am I always all about money...

He hasn’t bought one single thing for this baby but he’s recently put thousands into the stock market and I get it he gives us a place to live but this doesn’t feel like marriage
