My boyfriend poured preworkout on me

My boyfriend and I got into a fight. Usually he has a loud voice and short temper so he’ll start screaming or something. I try to stay patient and calm but I’m not gonna say in the past I haven’t screamed back when he gets loud. Today I didn’t scream I stayed calm and I didn’t try to raise my voice. He’s got mad and poured out preworkout mixed with water on me from a full bottle. I just remember trying to move it but he is stronger so I couldn’t. He was laughing when it happened and said people would think it’s funny and understand his side. Also he said it was just him turning the bottle and it so happened to pour onto me when he said what he’d tell people the story was. He said he did it because I wouldn’t immediately get out of the car when we were arguing but the problem I find in this is a few days earlier he told me even if he says to leave I shouldn’t because he doesn’t mean it. I feel like it’s my fault but a part of me also feels like I was trying to do what he told me to do. I really just want some advice. Was this a fair justification for doing it to me? It burned my skin and made me itchy especially because after he did it I started crying and it was getting in my eyes. He later apologized and said he felt guilty especially because he told me to stay a few days earlier and then got mad I did. Is this abuse? I’m not sure. I’ve noticed he’s become a manipulative person recently as well he will tell me I don’t do something but when I give him examples of when I do it he will either say I only did it to use it against him or I pre planned it so that I could bring it up when I’m upset. I really don’t know how to feel. I’ve told him before that when he does that I think it’s kinda manipulative but he says yes but like everyone is manipulative anyways. I know he’s a quick tempered person but I am starting to feel like it’s my fault. Please if you could give some input and advice I’d appreciate it
