What to do when girlfriend's parents stand against love and she doesn't want to disappoint them?

Im 22 years old and my girlfriend is 21. Im a christian while she is from orthodox telugu hindu family. She lives in my neighborhood. We know each other from childhood. For the last one year things were different and we fell in love. She knew her parents wont accept still she got the courage somehow and accepted my love. 2 months back i met with an accident and broke my backbone. She cried for me and its because of her encouragement i survived the mental stress and got back home. The problem started when her mom read my messages in her phone. Her mom and dad said if anyone in the neighborhood comes to know about our love they'll have to relocate to some other place and she cant see her father again. This is what she said when i called her office phone. She says she decided to go with her parent's decision. She says she promised her parents and they are important. But after hearing all this i never got angry. I understand her situation. But i dont want to miss her in my life. I tried talking to her but she is so scared that her parents might commit suicide. I dont want to blackmail her emotionally like her parents did while i dont want to miss her too. I see her like my mom and never felt for anyone like this. She still loves me but hiding it so that i'll get tired of her and look for another girl. But she doesnt know she took everything along with her. Am just living for sake and would have been happy if i died in that accident than losing her and watching her walking away with someone. We dont talk often now cos her parents dont let her alone. Now how do i get her back? Im earning and am sure i can look after her better than anyone in her family. But her parents wont understand this. They talk about prestige always. She says her parents are not the listening type and anything i say will just hit their ears and they just wont think about it. My family doesnt know about this and im planning to tell them when she is ready to stand by me. Any ideas guys? Hope i gave all the details. Sorry for the really long question.
