its just my friend and her arguing nature .whenever we hang out together she asks my opinion regarding her top or neckless or her figure and if i say something negetive then she starts arguing that no its good. i dont understand that why she asks me my opinion at first place.She thinks everything she has is best.Once our other friend said to her that she should not eat too much junk because she is getting too fat{believe me she is very fat}then she replied"i dont eat that much junk and i am not that fat you shut up"Sometimes i say something like this which is beneficial for her but then also she argues .I am sick of this attitude of hers.we have fought few times on this issue.i dont want to lose her because she is my childhood friend but at the same time i hte her arguing nature .if i talk to her regarding this then also she will argue that she is not arguing...what do i do??
