competition: Worst Thing to do to a Friend

Well the worst thing a friend has done to me is she knew i was dating this boy that i had known for about 3 yrs. She went and told him that i was dumping him and that i never really liked him. That night she told me he was dumping me. So i called him and asked him why he was dumping me and he asked me the same question. Then i 3-wayed her and asked her why she tried to break us up and all she did was say no i didnt do anything. i would never do something like that, Well found out she hated me bcuz i was prettier than her and bcuz alot of people like me, i just dont understand her.. We arent friends anymore .. But in the end me and derick ended up staying together.. we dated from 3-20-09 until 2-15-10
