so much for being "friends"

okay..i really dont wanna name the people in this so i'll name the backstabber A and the guy i like B... we went for something in the morning in school and i saw B.. i was shocked..cuz B had told me the other nite that he wouldnt come..anyway..thn A came too..sheesh.. she kept asking me to associate with B..i didnt want to cuz i knew i would make it freaking obvious..so guess what?! A took her chair..and sat next to B and flirted with B for like half an hour.. IN FRONT OF ME!!!.. i was obviously pissed..i thought she wanted to help me or something..i was obviously stabbed in the back..HARD!!..sheesh..screw A mehn.. even C[a friend] was more pissed at A thn i was..cuz i didnt wanna make it seem that altho i like B, it doesnt mean that B cant have friends rite? but whatever..
