My Girl friend has suicidal thoughts

My Girl friend has always suicidal thoughts, when I saw her first time I said my family was not interested in you and she said I am going to suicide then I was forced to stay and console her...but then I am in other country now..from past 1.2 year last time I met her she was ready for marriage, but I said let us wait for some more time, I will convince my family and then we can marry..but of late she is out of control...she is always having suicidal thoughts....giving strict time line that if u do not come and marry by this time U will regret life long....she is meaning suicide..I want to come and marry her...but I am afraid now..because of all the threats of suicide she is giving me often, breaking laptop, breaking bangles...and in turn she got hurt herself... I like her, she is good girl...but threat and blackmail..I am afraid..not sure what to do ...please give me u r suggestions.. I said do not worry I will marry you, but I want u to have patience and go for counselling, u r not in steady mind now...my only concern is now a days laws are so biased and one sided for women only... If for small things tommorow if she says the same, then my life will be ruined....request u r guidance... I can come and marry her with that date she has given..but it is like only due to threat or force....I love her and want to marry her..but not with this state of mind... Currently spoke to psyatrist and thinking of counselling her..but she is not interested to speak to anyone...she already says if u complain to any body about this..to police or family members..then I will really die...so I am in fix...
