Advice?

I have a 6 month old and a 5 year old, I work full time and so does my husband. My baby is going through this odd phase where he wakes every night around 2-3am for a bottle. I’m trying to break this habit but I end up giving in because I’m just so desperate for sleep. After a sleepless night yesterday I was exhausted today. I came home for my lunch break and took a nap instead of eating that’s how bad it was. Tonight same thing, baby wakes up and starts crying extremely loud. I’m so tired I look over at my husband knowing there is no way he’s sleeping through this and I comment out loud - “next time I’ll pretend to sleep too and we’ll see who lasts longer”. He immediately woke up and told me he’ll stay up with the baby all night everyday but I would have to then pick up more hours at work because he’ll be scaling back to take care of the baby.

I’m so mad because although he does work a physical job, 5-6 days a week 12hrs a day, I also work full time 40 hours a week and then come home and cook, clean, play with the kids, make sure they eat, bathe, etc. it’s a full time job after a full time job. I’m going back to school next month and I’m so scared because I know I can’t count on him to pick up the slack especially at night when I need help the most. I don’t ask him to cook or clean or do laundry, but I expect him to help me at night with the baby. Am I in the wrong here? I just don’t see where I’m asking for too much?
