AITAH for asking my partner to take a shower?

Throwaway account just in case he happens to see this. For context, I, (22F) and my partner, (23M) have been living together for around two months now as I recently had a surgery. Things have been kind of rough for months leading up to it & they aren’t improved by the situation so I’m worried I might just be aggravated by the proximity and being an AH for no real reason. Night before last, we were sitting on the couch and he reached across me to grab something off of the coffee table and I was hit with some crazy BO, so I asked him if he had showered yet (he worked all day Friday & had only been home for a few hours) and he told me he hadn’t and wasn’t planning on it. I let him know that he should probably think about it since I could smell him and he got up and put deodorant on. Did not shower. Last night I got back to his apartment after spending the day with a friend of mine at a street festival. I was showing him some of the things that I bought while out, and everything was okay until I mentioned that I was going to go ahead and hop in the shower. He told me that he wasn’t interested in getting in and I asked if he had showered that day already, since he hadn’t the night before. He said no & I suggested he get in since I could smell him the night before on the couch. He got defensive and told me that it wasn’t my place to be asking him to shower & that I shouldn’t be doing that. It just seemed to really piss him off, and I told him that I didn’t really think I was wrong for asking my partner to keep up basic hygiene and to shower once in 48 hours. He told me I was being rude and from there, it just escalated into a huge fight. Am I the asshole?
