please tell me i’m not wrong for almost being at my breaking point in my relationship.

context- i’m a sahm, he works. i have a 7 year old and we share a 2 year old. i do have my own small income on the side plus child support from my 7 years old dad. i pay for all the children’s stuff unless they’re literally out of something and im broke. i get fs so he pays absolutely nothing out of pocket for food, if we run out of something before my fs day, i pay for it, usually about $100 or more a month and i only get about $400-500 monthly. i pay for all the household things- laundry detergent, dish soap, cleaning stuff, you name it, i buy it. i pitch in with bills when i can, paying the light bill, paying the phone bill, sending him money to help with the bills in his name. he tells me i don’t help out at all because i don’t drive, we have one car anyway so its not like it’s really effecting much at this point. he tells me that im useless because the house isnt 1000% spotless when he gets home- the kids drag out toys, my 7 year old trashes his room everyday, i try to pick up everything but it seems like every time i clean up one mess i come back and my kids have made more messes for me to pick up. it’s just a never ending battle. i feel like my whole life is dishes, laundry and being overwhelmed because i have no help with our kids even when he’s home. he told me i need to get a job or else, he doesn’t seem to realize that i would spend almost every last dollar i made on childcare because i know he wouldn’t watch them while i work. he constantly says things would get better if i worked but i know it would just be him taking all my money i had left from paying a babysitter and me still being broke.
