Unfortunately, you have every right to be scared. Your ex sounds dangerous, and you should take his threats seriously. According to the National Domestic Violence Hotline, "physical or sexual abuse is a part of one in three high school relationships," so a boyfriend or ex-boyfriend who is talking about doing harm to you or someone you care about is no joke. You need to speak to a trusted adult as soon as possible — like a parent, school principal or guidance counselor. Schools have strict guidelines about who can and cannot be on campus, so your school administrators should definitely be notified. If they can't handle it successfully on their own, they may have to involve the police and even get a restraining order to stop your ex from coming near you. You should not have to go through this situation alone, so please reach out and get the help and support you need.

What you should absolutely not do is go back with him, because if he is this angry, controlling and emotionally intimidating when you're not with him, imagine how much worse things will get if you are. The situation won't get better and it will be that much harder to separate yourself later. He's clearly a dangerous bully, and the last thing you should do is put yourself in harm's way around him. In fact, you may need to cut off all communication with him. Like we said, it is important to involve a trusted adult who can help you handle this situation. We can't stress this enough.

There are many resources for people who think they may be in an abusive situation. Contact the National Domestic Violence Hotline at http://www.ndvh.org/educate/teen.html or 800-799-SAFE. You can also check out the National Youth Violence Prevention Center, which has a special online area regarding this very serious issue at http://www.safeyouth.org/scripts/teens/dating.asp. Good luck, and be careful.
