Need advice/help to convince her parents to marry her

Hi, Guys. I am a boy from Bangladesh. I love a girl who lives in Pakistan. We both want to get married, but her parents don't want to get her married to a Bangladeshi person because of the different country.

I know that before marriage, any kind of relation is Haram. But our relation isn't like a typical boyfriend-girlfriend relationship like this generation. We start our communication everyday with salaam, and we inspire each other with Islamic things most of the times. We never talked on the Call. All we communicate with on Chat, though we saw each other. We are both almost the same age (28+)

I badly need advice/help about what should I do. I wish I had any relative in Pakistan who could help me manage her parents 😥. What should I do? How can I manage her parents?
