Cant believe her

ok, last year i met this person.  i had a lot in common with her.  she was very nice to me.  after a while we became best friends.  we did almost everything together.  we always had a great time together too.  shes ther person i started this blog with.  and it was also to help her too.  this year she was in a relationship and it didnt go too well.  i tried to be there for her but she just wouldnt let me in.  so i gave up for a lil bit.  then she says that im ignoring her all the time, but i wasnt.  i was there for her, i always was.  i was being a true friend to her.  then she started hanging around my ex; the one that i rlly like too! and she knew that.  one day i told her that i didnt like it how shes always with him.  i said that she can be with him when im not around.  so one day she gave him a great big hug right infront of me! and to make it worse, she gave me this real nasty look.  that bothered me a lil.  but i didnt tell her.  then one day we had to go to mankato for the drama day.  it was subposed to me hers and mine day.  we have been planning it for months.  i was one of the first ones there, then she walked in and i screamed her name, but then she turns to my ex and just gives him a huge hug.  now that hurt me, cuz she just ignored me the whole morning.  i didnt want to sit by her either.  then later on we got on the bus after a while to go home.  she wanted me to sit by her but she was being kind of rude to me all day.  so i sat by someone else.  then she started freaking out at me and just started calling me a jerk.  i made sure that i didnt say anything bad to rewin my life in school.  or even to rewin our friend ship.  so for the whole weekend we didnt talk one bit.  so i come so school on monday and i went over to tlk to her, cuz i thought it was one of our lil fights that we always get over.  but she didnt tlk to me, instead she gave me a real mean death look and just walked away.  it kinda made me upset but i didnt do anything.  so then the day went on and i was being talked about by other people.  they were saying that i was a horrible person and i hurt ambers feelings.  and i was sooo confused, cuz i didnt know wat i did to her.  i didnt ask her tho cuz she just looked really mad at me.  then it got to tuesday, durring school nothing happened durring school.  but while i was getting ready for religion, her sister called me yelling at me saying why would u do that! and i said wat did i to. she said that her sister told her that i made up a rumor bout her and her ex.  i just couldnt believe that she thinks that i did that! i would never do that to anyone!
