My heart is broken and i need help

i met this girl at a wedding. she was my partner in the bridal party. we exchanged numbers and we started talking and eventually fell in love. now somehow her parents and her family found out that we were talking and her family is calling her a tramp. and we aren't allowed to be in contact with each other. no phone calls, no instant messaging, no email. nothing. i really love her and wanna be with her. what can i do?
