Suicidal threats

MARRIAGE IN 2005. WIFE LEFT ME AND MY 4 YEAR SON(SUFFERING FROM BLOOD CANCER) IN JULY 2011.AT THE TIME OF DESERTION SHE SAID " I CANT SPOIL MY LIFE FOR THE SAKE OF ILL CHILD" .I TRIED MY BEST TO BRING HER BACK,BUT SHE NEVER AGREED TO COME BACK. THEN IN THE END I FILED CONTESTED DIVORCE IN DISTRICT COURT.SHE FILED TRANSFER PETITION IN THE HIGH COURT. AND SHE FILED A POLICE COMPLAINT AGAINST ME THAT  SHE  WANTS TO REHABILITATE WITH ME. BUT NOW I DONT WANT TO CONTINUE WITH HER ANYMORE. WE ARE ONLY TWO PERSONS IN THE FAMILY ME AND MY SON. SHE IS THREATING ME THAT IF I DONT TAKE HER BACK SHE WILL COMMIT SUICIDE. SHE IS LIVING WITH HER PARENTS FOR THE LAST TWO AND HALF YEARS.SHE IS ABNORMAL

1. WHAT SHOULD I DO TO SAVE MYSELF IF SHE COMMITS SUCH ACT ?

She cannot hold you responsible for such acts.  Lodge a formal police complaint to that effect as to she has got suicidal tendencies.  If she does, then she will go to prison for attempting to commit suicide.

2. WHAT PRECAUTIONARY STEPS SHOULD I  TAKE ?

When matter is already in court, you need not worry a bit.  Let her commit suicide is she wants.  But as I said, you file a formal police complaint and mention the same to the family court where you have filed divorce petition.  Collect evidences audio or video where she is threatening to commit suicide if she is not accepted back.  Further having suicidal tendencies is also a very good ground for divorce.

3. WHAT WILL HAPPEN AGAINST ME IF SUCH THING HAPPEN ?
