Being Blackmailed By Ex Gf For Sucide

my ex girlfriend is continuously threatening me for sucide, she has seperated from her husband in past , now she lives here in Pune alone ,I don't find her suitable partner for life and I don't wish to continue, she is asking for a baby without marriage and blackmailing for same , she has attempted sucide 2 times one when she was with her husband and second when she lost her job( she tries to blame me for this ) I live with my family and she is continuously asking me to move with her around 2km away from my home , I cannot justify the logic to my parents for same , neither I wish too, I m afraid of my life . I cannot live in a society imagining having a baby before marriage. All of my time and energy is consumed to treat her and keep her in a good mood feeling very exhausted and afraid of all this . I want to break all the ties with her and live a normal life again , Everyday I'm afraid if I fail to receive her call she could take any step .
