Relationship problem. How to end this relationship?

i am 24 year old girl. i am a teacher. before 2.5 years my real brother got married. his brother in law contacted me through facebook. slowly slowly we got committed with each other. in the very first year of our relation he was not much caring and was also flirty with other girls. we had lot of fights. then after 1 year i started talking to his best friend just as friend he started getting jealous as i expected and wanted. then a good point in our relation came. he started caring me and also giving me time. i was happy that our relation has come to right track but it was not at all at right track. he started caring me but became over possessive. now i am realizing that his actual nature has come to me now. he is not at all good for me because he is abusive. he abuses me a lot. on very small issues he starts abusing me badly and also becomes violent on himself like hurts him self beaks his phone in anger, hits himself and so on. when i say that i cant live with such a violent boy he says i will kill my self, i will come to your home today and will tell everything to your parents and then will kill my self and all and he emotionally black mail me by saying that he love me a lot. i am really getting depressed what to do. i cant live with him due to his bad nature even i do not know how to leave him as he says that he will kill himself. i also don't have guts. i am being scary day by day. i am getting depressed day by day. please solve my problem . what i should do? :'(

Hey hun, honestly... if he actually has the guts to kill himself for you leaving him.. then let him. That is in no way your issue. What you need to do is get yourself out of that situation and stay away from him. Maybe get a PPO or move in with family that he doesn't know the location of. Most important thing is getting yourself to safety, forget anything else. Life goes on. Things can be replaced, new jobs can be acquired. Just get out and stay away. If he hurts himself it has nothing to do with you. Its his issues and he needs to deal with them. It isn't your responsibility to deal with them. You have your own problems. JUST get out and stay away. Make a new life for yourself. You are strong, you are beautiful and you can be better than this.
