Pathetic!!
Part 1--Here is my past: I loved a girl dearly, but she died. It was tragic.
Part 2-- Ms. XYZ, your picture inspired me to write Part 1. You are as beautiful as she was; you are just like her. Infact, I believe, you are her. Please, accept my love. Please, I have gone through a lot, you have to except my love. Even if you choose not to accept my love, I will always see her in you. To me, you are her.
Bottomline--Emotional Blackmail.
Suggestion: It is entirely up to you to move on or not. If you decide to love again, love the person for who she is, not for who she resembles--love Smriti as Smriti, not Smriti as Sapana. Think of Sapana as a 'Sapana,' and forget her as a sweet dream, but if you decide not to move on, cherish the moments that you spent with Sapana. Hold on to those moments; let her live in your thoughts. Don't ever forget that there is-was-only one Sapana, and no one ever can take her place. She is too special to be replaced by someone else.
If I were you, I would choose not to move on. I would let her live in my thoughts, and cherish her forever without confusing her to be someone else. But again, easier said than done.
Good Luck!
