Would you dump someone who threatens to kill himself?

first off, the big question is WHY does he want to kill himself?
you would not withhold food from a starving man if he was complaining he was hungry would ya?
find out why he wants to kill himself, is it a problem that CAN be solved?

let me give you my point of view, I used to think about suicide all the time, but the reason why is because women never gave me the time of day, women would NOT date me BECUASE I was lonely, the whole point of being in a realationship was so you would NOT BE LONELY!

imo he's an attention whore she should break up block his calls and delete his number
very rarely does a suicidal person talk about suicide they just do it one day
she should however tell the parents if possible

DUMP.

Your friend's boyfriend is seriously mentally ill and/or abusive -- making threats to keep someone in your life is controlling and abusive. And if your friend stays with a guy like this, your friend has some problems, as well.

Your friend should get a brochure from a mental health facility, and give it to him when she dumps him. No contact with him afterwords.

first, I wouldnt' date a guy like that
second, I would get him to get help asap. I would treat that as a serious threat and I wouldnt' want to worry all the time my boyfriend feels like this. I would feel bad for him and he might just need your help right now. I would set him up with a counsellor , get him to talk to friends something or get him in touch withthe anti-suicide line where professionals can help him

It's not her problem. She can't stay with him and be unhappy just to make him happy. I doubt he'll do it. He probably just says it to control her. Next thing you know it's going to be, "If you go out with your friends tonight instead of staying with me I might just kill myself." It's a game and it's ridiculous. You are under 18 so I am assuming she is too. She should go to the school counselor and tell him what is going on and let the adults step in and take it from there.
Besides all that, if he acts this way he is going to bring her down with himself. Her confidence will lower, she will get sad, she won't feel right about anything including herself. Get her away from his damaging behaviors.

hel yeahh and then I would tell his paretns that he is a crazy and needs t0o0o g0o0o somewhere t0o0o deal with some iusses . If you don't wanna be with somebody then d00on't be with then it's thast simple.

Is he under 18? They all say that. Dump him.

I would break up with him. The thing with suicide is that most people do not talk about it if they are serious about doing it. He's got some teenage angst that requires some form of help in one way or another.

I think she should stay with him to help him what he's going though. So she can find out why he wants to kill him self and if she does find out why she can help him with his problems. After it she still likes him or he likes her pick if she should break up with him.
