Do fed up situation result in lost of feelings?are these lost temporarily or forever?

My gf of 3years got fed up due to the disputes we had the whole week n asked for break up n reason she said was that she got fed up....she seemed confused or may b lying abt her feelings "first she said i lost my feelings for you after half an hour she said no i still love you but dun wana be with you,second day she still said that i lost feelings completely and 3rd day she said it was jst an ifatuation"

she has changed her all contacts
um totaly confused what she is trying to say

is she fed up thats why for time being she is not realizing the feelings she have for me? or due to this fed up condition she has temporarily lost her feelings? um totaly confused
