My best friend committed suicide after being d...and it's my fault..?

First of all you didn't do this to her. Yes it was horrible, yes it was awful. But you did not cause this. This guy that professed to be your friend did this to her to make her feel so bad for this to happen, I am sorry that it did, BUT IT IS NOT YOUR FAULT!!!!! Her parents are upset and looking for someone to blame. Do you wear a cape around your neck? Are you Superman? Can you see through ex ray vision to know that some awful person will do something that will scar or hurt someone so much that they need to go to that extreme of suicide? Stop blaming yourself and a weekly *** kicking or even daily should take care of this dude who is a punk to take advantage of a girl who had a little too much to drink
