idk what to do anymore

so me and my boyfriend are about to make 6 months and these past six months have been above and beyond amazing! i love him so so much and he is so sweet but there is one issue. i hate how he acts when he gets mad. he is so determined to win every argument and wont drop it until he does, raises his voice, and gets so annoyed so easily. i know yall will say talk to him about it but when i try to talk to him about how i feel he will get mad! it really upsets me and idk what to do.
