AITA for leaving my friend at an aquarium during a hangout?

Hi reddit. I’m using a throwaway but this isn’t my first time scrolling here.

So I (18f) and my friend (20m) made plans for an aquarium “date” for valentines. We are both the only single people in our friend group and are pretty close so it was kinda like a friend valentine thing. We were both excited as this is a new opened aquarium in our area and my friend really loves sea animals. I don’t know much about them so he likes to talk to me about fun facts and such.

The problem started when we were walking around looking at the bigger animals. It was really busy with mostly children. We were looking at some big tank when we heard kids next to us talking about the animals. They were (obviously) joking about one of the bigger fish eating all the little fish and that’s why it was so big. My friend scoffed beside me. I laughed it off but he got increasingly frustrated as they kept talking about it. He then turns to this 12 year old ish kid and says “actually, (the big fish) doesn’t eat other fish. it’s naturally that size, smart ass.” I was genuinely shocked and turned to him, he shrugged and I turned to the kids who looked scared and they whispered then walked away.

I said to my friend that I know he loves sharing facts, but they’re obviously just little kids making jokes, and that he didn’t have to scare them away. He said he didn’t scare them, he was correcting them on spreading misinformation. I said he was obviously older and they were barely in high school, they probably got intimidated. He said “yea okay, sorry” and we moved on. We get to another part of the aquarium about half an hour later and he’s looking at the seals and asking the workers about their routine and stuff. I kind of just let him nerd out and I just watched. Then my friend started pointing to one of the seals saying, “this one there looks too skinny. Do you feed him properly? I doubt it.” And started arguing with the workers about “neglecting” their animals. I tried to de escalate and tell him the seal looks happy and fine to me. He told me I don’t know shit about animals so he doesn’t care and he kept arguing with this worker who looked pretty stressed, trying to assure him they feed the animals.

This is where I may be TA. Me and my him had come together in my car. I told him we needed to leave and he was making a scene. He said no and he wasn’t done looking at the animals. I said “well, I’m going. You can come or you can stay here.” He called my bluff and told me to leave so I did. He called me five minutes after I drove off screaming because I left him with no ride. I told him I said I would do it and he was being embarrassing. He started crying and I hung up. Some of our friends are saying I was TA for leaving him there without a ride and not backing him up. My friends and one of his friends are saying they also don’t like going out with him to things that interest him because he always acts like that and they wish they’d drove off on him at those times. AITA?
