I am divorced and have been in a long distance relationship with a lady for 18 months now. Everything was good in the beginning but I slowly discovered that she is extremely insecure, aggressive and very very dominating (she is an educated lady with a very good income). I suspect she is not mentally stable but it hasnt been diagnosed. Over the last year I have gone through inhuman pressure and emotional blackmail and I no longer feel that this relationship is a healthy one. I have made several attempts at ending it in a nice civil way by means of discussion and dialogue. She displays extremely violent and uncontrolled behavior every time I have tried to stop this relationship and has been constantly threatening me and taking uncivil actions to make me lose face among my social and professional circles.
In brief : Two suicide attempts, Fake evidence of pregnancy, hacking email IDs and checking it regularly, stalking phone-calls to my office, colleagues & ex-wife with various weird demands, forcibly demanding that I marry her soon, constant blackmailing with threats to commit suicide - threats to yell and shout in public view at my residence, has also threatened to stab me once - came very close actually.
No cohabitation (max period is 30days - once), no joint property, no kids.
What are my options to prevent her from continuously doing this to me and my work? It has already continued for 10-12 months now. Whats the process of getting a restraining order?
