It seems that way because she IS moving on! And you've got to let her. Detach. GAL. Leave her alone. Somewhere down the line she's going to look back, and when she does if she sees a sad, desperate needy you then she will look forward again and stay on her journey without you. However, if she sees a strong, independent, content you then she may be attracted back to you.
What I am saying is right now she is done and moving on. Later? That could change. It depends on what you do with yourself.
