Dear Querist
My opinion on your queries are as under:-
1.What should i do now?
Opinion:- either forget your job or live with her peacefully if you want
or immediately file a divorce case against her before family court based on cruelty U/s 13(1)(ia) of Hindu marriage Act-1955 without thinking about the consequences about your Job, otherwise if, you live with her, there will be apprehension always in your mind to lose of your job and if she is cunning then she always threaten to you for your wrong.
2.Will my govt job be affected on unmarried basis? or
Opinion:- if you did not mention about your marriage and based on unmarried status you got the Job then it is a wrong declaration intentionally and based on that information, you may be terminated for the same.
3.Can 'mistake of fact in declaration' help to defend my job?
Opinion:- Not at all.
