HELP!!!!!!!!!!!What the HELL should i do now!!!!?

dude if she is your BEST FRIEND then she will understand. its not like its the end of the world rightz? so what. i think that she should be happy for you cause she is your friend. that happened to me once. the guy the my BEST FRIEND FOREVER liked since elementry (we are in high school) kissed me at this party and she was in the same room. so i guess she saw it or somebody told her, because the only thing i saw was her running out of the house. but we are friends now, and i still talk to that guy, so if she your real friend she wil understand. and i think that you are the one who needs to tell her, cause she will be mad to hear it from somebody else.
