Dear D&D:  I have a better question.  Why would you want her back?  Yes, I know, you had fun, were falling in love, etc.   She obviously doesn’t feel that way.  One of the two fastest ways to heartbreak is chasing someone who doesn’t reciprocate your feelings.  (The other way is chasing someone who does reciprocate your feelings. Go figure.)  Anyway, use your charm that worked to meet her and work on meeting another woman who will share your feelings.
