What should I do.. Should I call her?

I truly feel sorry for your situation, however I believe that you need to confess your feelings. Maybe she will re consider if you show her how silly her parents wishes are. Why would you marry someone you don't love? Marrige is for two people who want to spend the rest of their lives together. Why on earth would you spend it unhappily married to someone? Ask if she'll talk it over with her parents and then try to talk to them yourself. This shows your love and dedication for her.
