Kya ye sahi ho rha hai?

My boyfriend screams at me when he's angry. It's been six months in this relationship. He says that couples yelling at each other is normal—fair point, I agree. But why is he being disrespectful? He tells me things like "You never do XYZ" or "You always do this," and honestly, all of this has made me so numb toward him because if I have no value to him, then what am I supposed to do? Plus, his tone gets extremely disrespectful, but according to him, it's fine as long as he's not using actual cuss words. I can’t even talk to him about my problems anymore. I have to give my 200% every single day, or else he gets all passive-aggressive and distant. Is this normal? Considering I have board exams and entrance tests coming up, I asked him for some support, and instead, he became passive-aggressive. Now, whenever I talk to him after a long study session, he tries to act like some savior and keeps saying in a passive-aggressive tone every ten minutes, "Go study, it's time." He makes me feel so guilty just for existing. It literally feels like I’m chained. And if I question it, he throws four of my past mistakes back at me. What do I even do?
