I can’t grasp what my BF confessed to me

My BF has been angry for the past three weeks, ever since he brought me flowers (which he never does) and I don’t react how he wanted me to. He didn’t communicate he changed our plans from what he usually would do when picking me up from work, and my memory isn’t as good as his. He told me yesterday that I yelled at him in front of others, because I was embarrassed to be so sweaty after working a shift for five hours and wanting to go home. His surprise change of plans I didn’t appreciate and all I wanted was to go home. He never buys me flowers so I didn’t know how to react, but apparently because I didn’t react the way he hoped, he decided to intentionally take revenge.

I’m not even sure if I believe him, that the last three weeks of his anger issues and abusive treatment of me has a reasonable explanation, that he wanted to take revenge out on me because I hurt his feelings accidentally despite not intending to. I even apologized on the day of, saying I was sorry for how I acted.

I can’t comprehend that I’m with someone who could punish me with such intention. He wanted to hurt me, and he did. So much so I cried at work and was desperate for relief, and made a thoughtless decision I wouldn’t have made otherwise. I pretended to be unaffected by his treatment of me until I broke, and the only place I found refuge from his abuse turned into a place that rejected me because of a single mistake.

Either he’s lying and trying to justify his mean behavior, or he’s telling the truth and did want to get revenge. The latter scares me, because I didn’t think he was capable of such cruelty. To do that to someone you love isn’t love, obviously, and having grown up walking on eggshells because of my narc mother doesn’t make this ok. What should I do? I’m just in shock, that I love someone who would want to hurt me on purpose. I’ve been reading the book ‘why does he do that’ and have put it into practice to continue in survival mode the only way I know how. Thanks so much for reading. Also, he said he was going to break up with me, but instead spent the last three weeks disrespecting me and abusing me. What should I do and idk how to feel anymore.
