Ok, this is freakin' annoying! Help!!! :/?

Ok, so, I was at a dance last night. I was hanging out with my friends and dancing and stuff, having a really good time! But then something happened. This guy I know, really likes a girl who's my friend, who already has a boyfriend may I add. He's a senior, she's a sopre. He has the maturity of about a 5th grader, read on and you'll find out why. He really wants to get with her, and whenever he knows he can't, or she's not paying enough attention to him, he'll basically just sit and sulk. Well, last night things just went way too far. He just all of a sudden takes a huge face plant into the ground, and pretends to faint. It was staged, you could tell [read further, and you'll find out why]. Then, all of a sudden, every kid starts to come over and crowd around, officers, paramedics, teachers, everyone. It was a freakin' frenzy of people. AND you could tell [or at least I could, the other brain dead people couldn't put together the clues] that if he took a huge face plant and it wasn't staged, he wouldn't have protected his face in any way. And therefore, his nose would have been bleeding and such. Well, he got back up and it wasn't. So obviously he protected his face in some way. And also, when he got back up from "fainting", after like 3 mins [hmmm, short time....funny how that works]. He was all smiling at the girl he likes, and taking her hand and everything. IF he really fainted, then when he "woke up", he would have been groggy, head ache, dizzy, out of it, etc. But he wasn't....he was smiling, and if someone really fainted, they definitely would be doin anything but smiling. AND an ambulance came. His sister RUSHED to the school, because of course, she thought it was real. All because of his little "Oh, maybe I can do this to gain attention from her" hoax, he caused a whole scene/frenzy/panic. It ALL has to be about him. He just did that so he could gain attention from her. Hence why he was smiling at her and everything. ALSO, he had a choice. He could take ONE friend to go back home with him, and of course, he right off the bat picked her. And then when an adult offered to drive him home, he said "Nope, she's coming with me!" Cause he wanted to be alone with her, and he likes her. Also, when me and her would start dancing sometimes, he would always have to chime in and interrupt.... because he felt "jealous". And now, people still refuse to believe it wasn't true. Ok, so I was talking to this girl about it. I didn't TELL her I didn't think it was true, I told her I'd need further information about it. So then her friend I'Ms me [who USED to be my friend, and who's a freakin' mess may I add] Oh shut the hell up, it was true! Then she starts like sayin all these WICKED stupid insults. She's 16, but get rid of the 1 from that and you'll find out what age she was acting on I.M. So now, me and her are under bad terms. Me and the girl I was talking to are still friends, but if the little ***** that was I'Ming me gives people the wrong message, then that could turn people away from me. So what should I do? Please answer! :) Thanksss! :)
