Girls take any step to acheive their Objective.
In my Opinion, she will never commit suicide, it is to pressurise you to marry her.
If she really lovers you, she will not leave any suicide note against you.
If she don't, She will not suicide.
You may lodge complaint that a particular girl (Not ur gf) blackmailing you, and compelling you to fulfill her demand illegally.
Send Smilar Notice to her and her parents for ionformation.
The Relax, Remember, no one will suicide.who threates to suicide. Barking dogs never bite.
The Woman threat befor u marry, they aslo threat DV Act, & 498a 125, after u marry, & now a days man is at their mercy!!
{Even if they bite, we have anti doses Give me name & address of ur gf , i will inform certain authorites.}
