Wife desserted me

Hello Team, My wife has left me and gone to her Parents home past one and half year. I have tried all the methods to call her back, though she had blocked me wherever possible. She wants me make a separate home near her Parents home. And I stay 400 kms away. I can't leave my parents just because of her. Can anyone guide how do I approach for divorce. If I go for section 9, definitely she will make lots of false allegations against me ,my family members. please do guide on how to approach for divorce
