tell her that u comepletely understand her feelings, but tell her that u need to know whether she wants this relationship or not. give her all the time she wants to decide, but dont let things go further until shes made up her mind. shell either decide that she wants to be with u or that she doesnt want to be with u. if she does, then i respect her trust in u. if she doesnt, then i think she needs some time without u or any guy so that she can heal mentally. i feel for u though, because its not like its ur fault her ex used her.
