Told this guy I was hooking up with that it's not serious and his reaction seemed "petty". Did he sound surprised because he didn't think I could have other options ?

Been seeing this guy to hookup. We met up the other night. I've been asking him if he could get an updated std test (he keeps saying he will but hasn't, so I called him out on it and got annoyed). We got into a 5 minute argument about it. I said a bunch of things to him, said exactly what was on my mind about this, but this is the only thing he had a reaction to: I told him "I feel like you think getting tested makes things serious. You can see whoever and I'm doing my own thing". (This is the **first time we ever explicitly talked about this too). He sorta scoffed at this, like "ugh". And then later, towards the end of the argument, he said something like "well like you said, that it's not serious, we don't have to keep doing this anymore".

Then he asked me to leave so I said okay and thought that would be it. He messages me 5 mins after and says "My bad whatever happened, dw about it". I tried calling a few times cuz it's easier than texting (also I'm drunk) but he didn't wanna pick up the call. I told him not to text and drive and he said he's not and then "But see you probably never" (okay??). Did he get bothered that I told him it's casual because of an ego thing? His reaction kinda bothers me because I'm sure he has other options and I feel like he didn't think I would have any...
