Hello,
First of all for the reason you stated you can not file for Divorce.It is not a valid reason.
Secondly you need tio have at least an year of separation or complete an year fromdate of marriage to file for divorce.
They can file a case under 498A.
Accuse you of domestic violence,cruelty,harrasment,dowry and ask for maintenance and alimony and file police complaint.
Best way forward is to talk to yopur spouse, get her ready for a mutual consent divorce and file for divorce after an year.
