Some people are never satisfied

Just need to let this out. I'm so sad right now, my 2 yr old is watching me cry and is wiping my tears. Well she went #2 and i asked my so if he could change her diaper this time and he made an excuse not to. He said he worked all day and shouldn't have to. I told him just bc he works, doesn't mean he doesn't have to be a dad. Then he gets mad at me and tells me to be a mom and asked me what i did all day beside sleep. I am 9 months and due in 2 weeks or less and am always tired so i nap sometimes during the day. Our daughter is always bathed, fed, the house is always clean, everything always organized idk why he's never satisfied. He calls me lazy and says i never do anything all day while he's on his feet working. What does he expect me to do, build a house? He only feels bad and apologies when i cry bc what he tells me. I always tell him i don't believe it bc it's the same thing every time. I don't understand why he can't help me. I only ask to change her diaper once or twice, nothing else. I really feel i will have to do everything for both kids when my next one is born. I have to in his eyes since he works. I thought these were his children too and it should be equal. . 💔
