How do I leave my angry, depressed, suicidal, live-in boyfriend?

i would contact a mental health hotline, or clinic and ask them since he is suicidal... and when you are ready to leave contact the law or at least have a friend (perferably a large male) go with you to get your things.. because he sounds like an abuser to me.. it may not be physical but it is emotional and mental and this is not good for you.. but the easiest way would be for him to be admitted to a hospital somewhere for a mental evalutation and take your oppertunity to leave.. most states have a state run hospital who with treat regardless of your ablilty to pay... and if all else fails go to the police.. tell them he has said he will kill himself if u leave and you have to get out for your own sanity, they should know what to do
