Idk what to do

Everytime I say how I feel to my boyfriend he disagrees and gets angry. Like he would do things to get me mad & when I try to express he gets angry and starts screaming at me. I tell him to relax and he doesn't . I feel like your boyfriend shouldn't yell and curse at you just for saying how you feel. I don't curse at him or be disrespectful at all for him to react that way.
