My girlfriend [18F] wants to end our relationship [18M] because her parents might not approve of us due to our different races. How should I handle this situation?

I'm from India, where caste differences are a significant issue. She mentioned that she can't upset her parents and cannot go against their wishes. When I asked why she hadn't mentioned this before we started dating, she admitted that she thought she could manage her parents' opinions. However, she now realizes that they won't accept our relationship.
