I'm sorry but if you're in a relationship with someone who is suicidal, don't be afraid to break up with them. If when you started dating them they mentioned it to you and said how sensitive and serious it was theyre basically telling you if you leave I will hurt myself. That is not a good position to be in! I know I had a relationship like that too and it just feels like you're being tied down...no one should have the responsibility of another's life especially like that. They'll feel like a lifeline and like that you can never leave....that's not an okay thing to do.....theyre guilt tripping you into staying with them...if they are really that suicidal and you're scared for their safety please get them help. Call a hotline or get them to a therapist but no one should be held with a burden like that.....
