Is this normal in a relationship?(update)

My boyfriend and I were fighting at home. This lasted for at least an hour and all we were doing was screaming and talking over each other so I finally shut down and said I am done talking about this. Then he started texting me while we were in the house so I blocked his number and even told him I’m blocking it because I don’t want to talk right now. I said I was leaving to go get food and he accused me of possibly meeting up with another guy?? He always says shit like that whenever he’s mad. I’ve never cheated or done anything to make him think I would do that but anytime I’m unhappy and want to talk about our relationship he automatically assumes another guy must be involved and that’s why I’m acting different. It’s so annoying. So here I am at Portillo eating a hot dog and he called me from an unknown number several times. So then I had to block/silence all unknown numbers. This is my call log right now. Is this shit normal??

Also wanted to add, that he just had surgery on his cervical spine. I picked him up, dropped him off, got his meds, soup and crackers to eat, I set him up in a recliner with pillows and blanket and served him all day yesterday so he could rest. Part of our argument today was that i didn’t make a social media post about how his surgery went so therefore I don’t care about him as a girlfriend, he even went to the extent of saying “Danielle even made a post” which is his child’s mother who is barely involved (he has full custody). That sent me off the ledge that he even had the audacity to say that. He makes a huge deal about social media and all I do is post memes. I don’t even post about myself. And he always says I act like I’m not in a relationship on there when I have uploaded our last photo less than a month ago, plus posted a photo of his daughter with her new gifts I got her for her birthday just two days ago, even made a post about how to get chlorine out of her hair. And it’s apparently not good enough. He is 28, way too old to care about social media in my opinion

UPDATE

I decided to break up with him and now he keeps calling me a piece of shit for breaking up with him a day after surgery. He’s called me that at least four times today. He said I’m fake for being nice to him up until now. He also keeps saying I probably have someone else and I’m not telling him about it.
