I have no idea which IPC it could be and it is critical indeed

Hi Team Actually I have no idea what case it could be but I was sharing an apartment with a girl to whom I always kept clear from my part that I can not and will not Marry her in future. As the days came closer when I had to move out she called her parents and pressurised me for marriage. I said no and then that time they started threatening me for police case and all. Somehow I said yes to avoid the situation but with in a month of that I resigned my job and moved out of India. Now I got to know that they send police to my office and also the same girl has contacted almost all of my contacts through Facebook. Recently police called in my hometown as well. May be they got the landline number from directory and asking about me. They did not give us any info about any case and all. What it could be? Can someone please guide? And will it be a fir or formal complaint. Also got to know that the girl and her mom has published it in local Andhra newspaper too. And will it be coming under criminal law?
