Threatening with 498a

Hi,

I am from Hyderabad. I got married 5 yrs before and we were happy since last five years. but that has become my assumption because all of a sudden she went to her home and has returned back for 2 month and when I asked her after going home she told me that she need a divorce. Ours is inter cast marriage. to my surprise i found she is very planned and took off all her belongings well before she went home. Now after 3 months of silence and my continuous effort to convince her she wanted me to give 6 lakhs threatening me that she would go legal and file 498a on me. So what should i do now, I have not taken a penny from her but as a gift on some occasion or festival like that they have given both if us around a lakh or so. Please suggest me what should i do before they take any adverse action against me.

Regards,

Kanth
