Am I in the wrong on this?

So to start off, we have 5 kids, 7 and under (set of twins). I'm a SAHM, I do have a small buisness that I do from home, and I do all the child care, cleaning, cooking, and get all the bills paid, I do all the shopping, I homeschool the kids, etc. My husband has a full time job, he goes to work, comes home and plays on his PS5. Literally just about all he does. Sometimes he'll do yard work, but never lifts a finger to help clean, and very rarely helps with the kids. He works 2nd shift and goes into work anywhere from 1-3pm, his schedule is always changing.

But anyway, he wants me to go out and get a morning job where I'll be off at latest 1pm. I told him no, I have to much already going on. (Putting the kids in daycare would be pointless because I would just be working to pay for that). We aren't really struggling financially, but he likes to spend money and can put us in rough spots. He went and spent over $2000 on equipment to make t-shirts and is constantly buying stuff for that but hasn't made a single shirt at all! Its been sitting for 7 months now. I looked, and I can't find any jobs that would accommodate to what he wants me to get. (A job that pays at LEAST $18 an hour and latest I would work is 1pm). My reason for not wanting to do that is, MY life would be affected by that, I would have to get up early, go into work, come home and get the kids out of bed and do all the house work on top of that. I have to take the kids to the grocery store with me or put them all down for naps when he's here because he wont watch them. He claims he will take care of them in the mornings while I'm working but I know he wont. I just know everything is going to be piled up on me more-so and I just don't want to go through all of that stress. I'm just not sure what to do.
