Dear Mr. Venkat,
You are a LUCKY man that you have all the written mails as proofs.
But dont take time to file a police complaint against such a lady because if you will take some months and then went to polics then police will torture you that what happend today you have received these mails earlier and now why are you complaining after this much gap of time.
Your mediaters must be trying to sort out this matter and they all will advise you to clarify things in a close room but my friend when this lady and her parents will file 498 and other shi** on you nd your family no body will be there to save you.
Trust me and file a case to your earliest.
I am a suffering from the same you must not repeat this mistake.
Regards
SJG
