She wants to come back to me but can't defy her folks!

Dear Diana,

I'm 25 years old. I am truly in love with this girl. When I proposed, she asked me if I would marry her. I said I would. Four months later, we started fighting over small things. It wasn't my fault. She did some things that compelled me to raise my hand on her in her mother's presence. I apologised to her mother and her but they wouldn't relent. Her parents refuse to see me as a potential son-in-law and are unhappy with my job and financial condition. Moreover, she has directly said she doesn't want to marry me. To top it all, they even filed a complaint against me at the local police station for raising my hand on my girlfriend. Thankfully, I was spared the consequences. Four months back, she realised my love and came back to me but added it was too late as she was engaged to be married to another guy on April 11. I tried to tell her that she has to convince her parents. She replied that it was a question of prestige for her parents. She said she was unhappy and is going ahead with the marriage only for the sake of her parents. What should I do in this situation? She says me she loves me a lot but is helpless. But Diana, what about me? I'm suffering through all this. I love her a lot and want her any which way!
