I have been married for the past 6 months to my girlfriend without informing our parents because we wanted to live in a flat, now I cannot take the mental pressures from her side anymore. How do I go about a divorce, she has let my parents know about it, I have lost my job also. Please help

You go to an Attorney and file for divorce - the grounds don't really matter as long as they are legal in your area.

Whether parents know or do not know does not matter.

You may even "qualify" for an annulment.
