She broke up with me when I got sad and angry bcoz of her behaviour. Why?

She came back after a week from checkup, i told her that she is changed she doesn't love me or i don't feel the love and i have stopped saying i love u, and talked back when she gets angry on me and the next thing happened was she needs break from our relationship and the very next day she broke up with me saying that if she gets angry then i should not get talk back or fight back doing like this makes me woman, she doesn't give me a proper reason and after breakup she told let's be good friends coz I have always seen u like a friend, but after three monts of all these heartbreak thing whenever I try to forget and move on with things and as always talk nicely to her she talks back rudely only to me and now she only talks to me when she needs me , and if i don't help her she tells that u r my close friend you know why I did ask help from you but still u didn't help , she is just getting on my nerves now but still somewhere I hope things get oki with us at least she be good to me
