I keep trying tpo apologize and hes cussing at me..?

I kept bugging my fiance about his sisters treatment towards me(actually i yelled at him). I realized it was muy fault , so i tried to apologize. Everytime i call , he answers so rudely, cusses at me, tells me "Youre drama e, f*** you,i hate you. you ruin my life, " and he goes on and on . I know I pissed him off, but do I really deserve this? In the end he'll say "you made me get so angry"
