Forced to break up with my girl?

me and my girl are over. she cried to me, i cried to her. i told her i cant be without her and will do anything and everything in my power and outside me power to make it work but she has ended it. her reasons being, her father does not know about us and its too risky. her father doesnt want her to ever (eventually) settle for a guy who is: arab, asian (all of it) and jewish (they're muslim). now im a muslim guy, i love her, she loves me. but unfortunately, bangladesh falls in asia so she says he will never accept it. i said i will talk to him in due time and she should have faith, but she said nothing will change his mind. i said when shes a grown woman, he might listen as shes only 20 right now, she said he will never listen. she still wants to be friends, i want to be as well, but its just so hard. the thought of her with another guy (doesnt matter when) just kills me. i have constant physical chest pains and have been to hospital already. im starting to break down as a human being.
