here are some more tips based upon my own experience. Honestly, reveal your past, and ask her to do so. Ask her if she ever really fallen in love anyone, if she tells no, know that she is still living with her past and she is yet to get over it or worse she is badly insensetive person because we all must have have fallen in love with at least someone in somewhere, sometime in our past. Only badly insensetive people dont fall in love at all or she is not being honest at all. Nobody appreciates badly insensitive or dishonest girl to be your girl of you life.
