I have a friend whom said he was going to get his old g/f back who broke up with him back really bad for what she did. He ended up sending a letter to her saying that he was going to get her back big time and that she would regret breaking up with him. He hinted to me that it he wouldnt even be near her but rather through communication. After looking through his aim profile, you would then realize that he was going to commit sucide. He told me that he was going to get her back at 7pm today, which is right after he gets off work. I talked to his older brother(freshman in college about it) and he told me that he's done similar stuff before. He also said that he's going to drop by his work and check him out. What should I do? BTW hes a senior in high school.
