trouble about bf work pay

So me and my bf just got a house we live in Florida we’re it’s around 2200 for a 2 bed house so we got it and we have a baby on the way first baby. So we got 2 rooms. Problem is I’m on bed rest and can’t work I get social security so I do get pay, we agreed I would buy groceries and I would pay the electric that’s the only thing needed and I was like that works since groceries are around 500-600 a month and the electric is pretty high and everything so I was okay with that. But my boyfriend makes 14 an hour he’s 20 he’s grown and a welder a very underpayed one. It upsets me since I made 18 a hour working at the grocery store. He can’t even afford anything and uses his credit card for everything and has a very bad credit and it’s getting to a point where it’s all I hear about. And to pay the rent he has to get another job and work a lot when I don’t understand why he won’t move to a different place the average weld pay is 30-35 and he’s making 14 but every time I bring it up he gets all mad when I just don’t want him to to struggle. What do I do?
