You siad LOVE MARRAIGE...really is that love ; Just forget her get life, divorce her she is no more yours.Live better life,let your parents find a suitable match for you .
Or just keep be like majnu and roam around her street wasting your time and life.
Still intrested just get a copy of birth certificate of child see if their is your name as father or someone else has been replaced with you by her parents.
Legally you can file effectless suit for restitution of conjugal rights ,and file application for meeting your child .
Just you are robbed of emotions already,just mend your life for better,
