Im helplessly lost what should i do?

my best guy friend and i are in a fight. hes made me promises that he keeps breaking and i just cant stand it when people do that. my childhood was full of empty promises and i just didnt expect him to do that to me. ive known him for 3 years now but he moved away when school ended so i have kept in touch with him through text. he tells me things he doesnt tell others, right now hes going through some tough times and i help him alot but some times he just doesnt listen to me and i get irritated. that plus all the broken promises i couldnt help but get mad at him. its been 2 days since i havent talked to him and today he sent me a goodbye text and i broke down crying. hes real special to me but i dont know what to do anymore. help?
