dont do it tell someone.
This is a serious situation that needs to be addressed immediately. Please talk to a trusted adult such as a parent, teacher, or school counselor about what is happening. They can help you take the necessary steps to ensure your safety and well-being. Remember, it is important to never give in to any demands or threats from someone who is harassing you.
Approach him with your friends and tell him to leave you alone. If he doesn't stop, go again and tell him to stop or you'll get the police involved because he's committing a crime with stalking you. If he still doesn't stop, call the police and tell them about everything.
report him
he is stalking you
he's constantly around you or if he keeps trying to talk to you.
dump him
You should say, if you don't care about hurting his feelings, "Why the heck are you following me? You should be ashamed of yourself, you freak!" and walk away. Do not make eye contact. DO not talk to him after that. If you want to be nice, then say, "Can you please leave me alone? I need to talk to my friend because we are in an argument. And I want to do it alone." Say this to him over and over, and eventually he will get the hint. If he doesn't, you have no choice but to be blunt and obvious and tell him to BACK ON OFF of you. I had a weird stalker and I just ignore him. It's really annoying because he's my ex-boyfriend but these tips worked pretty well for me!
If your friend keeps blowing you off, I think that you should confront him/her about his/her behaviour in a cool, calm way. My advice would be to talk to your friend calmly and ask why they blew you off. They might have a very good explanation!
Tell him you're really not interested.
* Yes, it's called stalking! She should let her parents and the school counselor know this is going on. If the ex is warned and does not comply then she should have her parents put a restraint order on him. For now,she should always walk with at least one friend or a group of friends and try not to walk home alone. Even when going out on the weekend she should be around friends (letting her parents know where she is going and approximately what time she will be home) because if the ex turns up at the school then he is watching her and most likely following everywhere.
Well, frankly I don't think your friend is good friend if he is trying to take your girl. Maybe you should find another friend who will respect you.
Calmly remind him of the fact she is already with someone, and ask him to stop.
He likes the way it sounds and likely has interest in you or he could be just trying to bug you.
