Re: heart or mind?
Some random guy you met on Facebook that lives in India?? Logistically, how are you going to have him meet your parents? You’ve never even met him yourself! 
If this was some guy in the same city or country as yourself, you might have a fighting chance and the advice being given to you would be a little different. But from what you’ve described, there really doesn’t seem to be much a future there to plan for. Do yourself a favor and cut things off for good and move on.
