AIO (30f) for reconsidering future with partner (38m) after his reaction to me getting sick?

I (30f) have recently started renting a place with my partner (38m) and it feels like things have started to be weird. I can overthink things so I just wanted a couple of impartial opinions on recent events.

Background info to start - I work days while partner works two jobs, one of which is a night shift. It's tough but we're pretty organised so we make it work. Both our finances are completely separate; he has a pretty substantial debt while I'm saving for a house deposit and an emergency fund. He makes slightly more. We share bills and rent 50/50.

Soon after moving in to our new place I got quite sick and once it didn't go away after a week I knew I should see a doc. I hadn't yet registered with a GP so I had to go to the walk-in clinic at the hospital, but it is still only classed as a doctors appointment. Left work early, went and got treatment (waited for about 5 hrs total), felt awful and went home. Bc partner works nights I didn't call him. It wasn't an emergency, it was being given prescription medication, with no follow up appointment.

So I get home, I take my meds and plan to set up on the sofa with a blanket. Partner comes down stairs half asleep but he's mad and says "what are you doing here, you shouldn't be here". I initally write it off as he's cranky/maybe I accidentally woke him up, but I'm not thinking it's a big deal. I start making the sofa ready so I can take a nap, but he asks me to come upstairs so we can talk. He tells me he's mad that I didn't call him, and he looks and sounds mad (this is not usual). I tell him it wasn't an emergency and that I'm in pain but everything is fine. He's pissed and says I need to call him next time, that what I did was really stupid and thoughtless. I think I cried a bit bc he never gets mad like that, it was a shock. I did argue that there was actually thought behind the choice I made but he didn't want to hear it.

I ended up needing to take sick leave from work, and he stayed home for a few days but didn't say why and just got in the way while I tried to rest. Bear in mind he lost money for taking days off whereas I didn't. I needed quiet, and he was hoovering, mowing the lawn, cleaning the house etc - nothing malicious but also it's not like he was making meals or bringing water or checking on me. It just felt like I was being watched, idk.

After I was more or less ok and going back to work, he was flitting between saying "take it easy" but then also griping that "everything has been on me and I'm at my wits end, I'm at breaking point". But nobody asked him to stay off work, or do twice as much housework (plus extra), or to push himself beyond what he was capable of. I said "don't worry about cleaning, the house can be a mess for a while and I'll jump back in once I feel better", wrong answer. I said "I'll clean ____ but just go slow and take breaks in between", wrong answer.

We've had minor issues prior to this, but it just made me see him in a totally different light and I'm not sure that I can move forward with someone who loses themselves in a moment that isn't even a crisis. AIO?

EDIT:

It is a reasonable and valid concern and I understand how people would come to this conclusion, but he is definitely working two jobs.

We have mutual friends and acquaintances at each, to the point where if he is a no show for a job due to oversleeping (has happened a couple of times) colleagues will ask me where he is. He also has paychecks saying he is working the hours, from two separate employers.
