Was i right or was she right?

i knew this girl since we were kids every one seemed to think that we will become a couple when we grow up but when we did we still called each other and texted allot (as friends) i never said any thing about love and such nor did she. but one day she called me and asked me if i love her and she told me that she wouldn't feel sad or angry if i didn't and i told her the truth that i see her as a sister and a friend, but then she started to cry and sending me messages about betrayal and that i wasted her time and the she sacrificed so much for me, it went for weeks us sending messages i told her that its not my fault and i always saw her as a friend but then she went berserk and started talking about karma what goes around comes around, and that she wishes that i have an awful life this kept on and on and on for nearly a month i couldn't stand that i told her its not my fault i never told her i love her we weren't a couple to begin with, after that message i replied with harsh words i said bluntly that your an emo crazy delusional ***** after that mage she never forgot these words and kept bugging me from time to time about them were not talking now the problem started 2 years ago and just recently we never spoke but we left it behind us each one leads there own lives now, so what do you think? who was right the only thing i feel guilty about is the harsh message but comparing it to her million messages i feel that mine was just a grain of sand comparing to her desert!
