My ex boyfriend will not go away

If you have told him plainly that you don't want him near you, if he shows up on your property, you have every right to call the cops. It sounds like it's getting to the point of him actually scaring you, and that isn't fair to you at all. Tell him that if he doesn't back off you will call the cops & file a restraining order. Tell him face to face, and find the biggest guy you know & have him accompany you. While you meet him, tell him that if he ever contacts you again you'll file the restraining order & if he shows up on your property you'll call the cops on him.

I've been in this situation before, and it's really hard to deal with, but if you threaten him with legal action, hopefully he'll listen to you. You will however have to talk to your parents about this though, because being a minor, you'll probably need them to go with you when you talk to the police, and if he shows up at your house when you aren't there, your parents need to be aware that it is a possiblity and that you would like them to call the police.

Harrassment isn't a small issue, and usually police will take you quite seriously if you need them.

I wish you all the best luck. I'm here for you... like I said, I've been throuh this before & I know how hard and scary it can be.

Tell him to keep away as your dad doesn't want an 18 year old around his 16 year old daughter and he threatened to go to the police (I believe the age of consent is 18 there), tell him you don't want him because he is too much to handle and you don't want a boyfriend, tell him he should keep away because your brothers are asking questions and you are getting so fed up that you are going to cave in and tell them his name.
This has done 3 things, 1 he has now heard that YOU don't want him, so far he is under the impression you can't be with him and thus not her choice, the threat of police investigation, no guy wants a paedophile case hovering over them and your threat to involve your brothers will make him worry about vigilante justice.
Should all of this fail then tell your father everything, take out an injunction (restraining order) and stop putting yourself in positions where you allow men to chat you up as legally underage, it also says a lot about a girl who is quick to state she is 16 in trouble because of age issues and set your profile as an 18 year old girl, take a little personal responsibility and care and stop hiding your age on here and I assume other places attracting the wrong people.

First, it doesn't sound like you cut the relationship off at the knees to begin with and this was your FIRST mistake in this situation. The second mistake was going behind your parents back, concealing what you were doing and putting yourself in a position that gets you in trouble either way.

Tell him it's over, you don't want to be friends, you don't want to know him and cut him out of your life. Delete his email/MySpace/twitter/phone number and avoid him at all costs. Notify your parents of his and YOUR behavior so they can step in if need be.

Next time he shows up uninvited, threatens to kill himself, or does anything else crazy, you MUST do the following things, in this order:

1. Call the cops on him. Press charges. I'm not kidding.

2. Tell everybody* you know about how crazy he's acting. Witnesses will scare him off. If you keep all this stuff secret, he'll just get worse.

3. Tell him you're not speaking to him until he talks to a professional therapist.

4. Do not speak to him until he stops acting like a damn stalker.

* Don't tell other crazy people unless you have to - they'll just use the story as a weapon against you. I don't know if this includes your dad or not. If your dad ever acts crazy or threatening to you, call the cops on HIM. I am absolutely not f***ing kidding about this. Abusive people will always get worse and worse and worse until you fight back, and fight back hard.

Tell your parents. NOW!

Judging by this guy's actions, he won't go away...
It will only get worse.

He is trying to get you to pity him, by threatening to commit suicide. If this Loony Toon is serious, then he really needs to seek psychiatric help...or frighteningly, he may consider taking you with him. Don't be alarmed. Just tell your parents, local police officers,and be careful!

This guy is harassing you & it sounds like he's trying to make you feel guilty and bully you and your friends into making you go back out with him. I know telling your dad isn't what you wanna do but it sounds like it's your only option for 2 reasons. This guy sounds like he needs help. If he's threatening to kill himself over you then sombody needs to know, an adult who can talk to his parents or whoever and get the situation handled a lot better than you can. And if he's threatening to hurt himself but hasn't yet and the situation is just geting worse he may resort to threatening to hurt you or one of your friends. You need to go to an adult here. And your dad may not take it well & he could get really angry & you could be grounded for a couple weeks. But would you rather get in trouble and be grounded or risk this guy geting crazy enough to hurt himself or you?

have you tried saying, "i'm breaking up with you"? because guys don't usually do well with hints. you need to be blunt and straight-forward and if he tries to persuade you, say "i've made up my mind." relationships need to be mutual.
and he's not going to kill himself over you, it's a tactic to make you feel guilty. if he were to kill himself, rest assured that it's not your fault because he clearly has other, much bigger issues. tell him that he's freaking you out and it needs to end, NOW. this dude is going to turn into a stalker if you don't get out.
