Dear Sandeep Ji
Thank you for the supplemental information. Now, I will make a prayer to you not to use phrases like "listen dear.." on the LCI form , especially in response to leaned advocates. It could get mis-interpreted and you may solicit a reaction such as, " who are you to say - listen".
Now, coming to the issue proper, you are a grown man with a respectable job and are quite capable of conitnuing the relationship with the girl. You have not mentioned your intentions - do you want to marry her ? In Indian law, if I understand there is no legal standing yet for domestic partners.
For a moment, lets assume that you can provide evidence that the girl expressed her love to you and you have reciprocated and it is mutual - now what. Now, your take is that the girls parents are preventing the girl from developing or encouraging this relationship. If you had a daughter, would you like her to have a relationship with a boy that you dont respect or one who has not yet won your respect as a father.
If you get a lawyer involved, the girls parents may lock you in a room separate from their daughter. Dont take panga with someones daughter who doesnt willingly give their hand to you.
If you elope with the girl, you are inviting more trouble to your life and limb- think carefully - anything is possible in India. You may jeopardize the safety of your own lawyer also. Leave the girl alone and focus on your career. Encourage the girl to study and focus on her own career, if she so chooses.Isnt it obvious that the girls parents have no respect for you.
Corollary - Try to win the respect of the parents of the girl. Love business will fade away. What will stand is mutual respect and trust which is concrete.
