Am I being insensitive to my exes surgery?

Hi all –

I recently got into a relationship with a guy from work. We have been dating for a month and he recently had a surgery on his stomach to take part of his intestine out.
I will give you brief timeline of events.
•I spent the night with him the day before his surgery, and drove him the day of. I stayed with him the entire time he was under, and was with him until around 8:30/9pm before I went home (his surgery was at 9 am).
•The next day, I visited him for a couple hours to make sure he was doing okay and then I went to the bar with a few friends cause it was one of their birthdays (which he was upset with me for).
•the following day he was released and I was there to pick him up from the hospital, pick up his prescriptions, and then drove him back home. While he was resting I went to the grocery store to try and get him some light foods because he wasn’t on a specific dietary plan. He was basically told he could eat whatever. I bought him the ingredients to make chicken noodle soup homemade, to which he never tried or said thank you for. That was fine, I understood he was not feeling well.
•I stayed with him the following two nights after his surgery to make sure he was okay but I had to go home because I had to go home to take care of my cats (someone was watching them in my absence).

I hardly heard from him after I went home. I know he was recovering from surgery so it didn’t bother me, but I still missed him. I would tell him that, and that seemed to bother him.
Then a couple days later he texted me around 5 am saying that he was going back to the doctor because something felt wrong. The doctors discovered multiple abscesses in his stomach and he made it seem like there needed to be a procedure done to take care of them. I asked if he needed me there because I was supposed to work that day. He said it was up to me, but he may need a ride. So I called my boss, explained the situation and he gave me off. I got to the hospital around 2:30 (I also live two hours away from him) and when I got to the hospital it was very obvious he was upset with me, and was interrogating me on why I couldn’t be there sooner. I explained the situation, also that the weather was terrible and he just did not care. He called me a hypocrite, and said that I’m just a needy little support blanket, and basically that I dropped the ball and he wanted me to be there to comfort his daughter. I left the hospital because he said he didn’t want to deal with me. Also, all the doctor ended up doing was prescribing him antibiotics and no procedure was necessary.

A couple days went by and he said nothing. When he did reach out his asked if I was still mad at him. I expressed to him how I felt, and he does not think he did anything wrong. Instead he blamed me for not being there for him and not having any compassion, and then blamed his frustration with me on the painkillers he was on and the pain he is in. Proceeded to call me a bunch of names and we ended up breaking up. I know painkillers can affect your mental state, but am I out of line here? I can elaborate on this if I have to but I can’t help but feel maybe I was a little insensitive.
