What If you fell in love with a gurl who cannot get over wtith her past?

How do we deal with a gurl who cant get over with her past relationship?! Its ridiculous right!? And to think (not for bragging) that many gurls want me... I dont know what to do man.. I just cant get closer to her because im just to shy..... well shes about my age and we have a lot in common... I always dreamed of her ever since we worked together... I never thought that it would reach like this because im the picky type guy... I think i fell for her because shes simple and especially very sweet.. I hope i can show her how much I really care for her one day....thnx guys for helpin me out.. I will be expecting great advises from you..^^
