I love him a lot but i am scared sometimes

I get scared when i make mistakes because my partner gets mad at me and i feel so hurt about it. I recognize that I misunderstood his instructions and i admit that i am so stupid for that. (Also English is not my first language) and he agrees that i am so stupid but said that i am not dumb because he thinks i’m smart, just stupid and illogical. I apologized a lot. He said i should be improving but i am not. I feel like he treats me the way he talks to the customer service on phone when he complains something. But the difference is, he doesn’t curse on the phone. He didn’t curse directly to me, but the way he talks to me it hurts. I feel like when he is on bad mood, he will constantly point out my mistakes even with how i walk. I wanted to tell him how i feel about how he treats me, but after we both calm down. He will show me love and justify that he did that to help me improve my life. I will just forget what i felt because i do felt that he really love and cares about me. He is a great supportive partner but i just get very scared of him when he is upset when things in life goes wrong. He decided we move in together, which is great, i appreciate all the sacrifice and effort. And now he hates the area i lived. I agree that people aren’t friendly and weird. But i think he’s frustrated that he lashes it out on me. I am trying my best to find a new job so we can move out and find somewhere we could both be happy.
